"none of those points disprove nationalism."
How about some information concerning the actions done by people to other people according to those who agree with Nationalism, and then some information concerning the actions done by people to other people according to those who agree with Federalism?

Reclaiming the American Revolution: The Kentucky and Virginia Resolutions and Their Legacy
by William Watkins
"Second, federalism permits the states to operate as laboratories of democracy-to experiment with various policies and Programs. For example, if Tennessee wanted to provide a state-run health system for its citizens, the other 49 states could observe the effects of this venture on Tennessee's economy, the quality of care provided, and the overall cost of health care. If the plan proved to be efficacious other states might choose to emulate it, or adopt a plan taking into account any problems surfacing in Tennessee. If the plan proved to be a disastrous intervention, the other 49 could decide to leave the provision of medical care to the private sector. With national plans and programs, the national officials simply roll the dice for all 284 million people of the United States and hope they get things right.
"Experimentation in policymaking also encourages a healthy competition among units of government and allows the people to vote with their feet should they find a law of policy detrimental to their interests. Using again the state-run health system as an example, if a citizen of Tennessee was unhappy with Tennessee's meddling with the provisions of health care, the citizen could move to a neighboring state. Reallocation to a state like North Carolina, with a similar culture and climate, would not be a dramatic shift and would be a viable option. Moreover, if enough citizens exercised this option, Tennessee would be pressured to abandon its foray into socialized medicine, or else lose much of its tax base. To escape a national health system, a citizen would have to emigrate to a foreign country, an option far less appealing and less likely to be exercised than moving to a neighboring state. Without competition from other units of government, the national government would have much less incentive than Tennessee would to modify the objectionable policy. Clearly, the absence of experimentation and competition hampers the creation of effective programs and makes the modification of failed national programs less likely."
So Federalism maintains a voluntary association where Nationalists do not. Nationalists offer the non-option to leave the Nation State.
Federalism is shown to be Free Market Government Services, where Free Market Forces tend to force quality up and cost down.
Nationalism is shown to be Subsidized Slavery of everyone, where dictatorial forces tend to force quality to nothing and costs skyrocket to a point at which the only people who can afford anything of value are the psychopaths, sociopaths, and their army of sycophants, because that is the type of people who get to the top of Nationalism, also known as Corporatism, National Socialism, Communism, Socialism, Oligarchy, Arbitrary Government, Despotism, Empire, and various other euphemisms.
Example 2:
Richard Henry Lee, 6th President of the actual federation known as The United States of America:
"But what do we mean by a federal republic and what by a consolidated government? To erect a federal republic, we must first make a number of states on republican principles; each state with a government organized for the internal management of its affairs: The states, as such, must unite under a federal head, and delegate to it powers to make and execute laws in certain enumerated cases, under certain restrictions; this head may be a single assembly, like the present congress, or the Amphictionic council; or it may consist of a legislature, with one or more branches; of an executive, and of a judiciary. To form a consolidated, or one entire government, there[163] must be no state, or local governments, but all things, persons and property, must be subject to the laws of one legislature alone; to one executive, and one judiciary. Each state government, as the government of New Jersey etc., is a consolidated, or one entire government, as it respects the counties, towns, citizens, and property within the limits of the state. The state governments are the basis, the pillar on which the federal head is placed, and the whole together, when formed on elective principles, constitutes a federal republic. A federal republic in itself supposes state or local governments to exist, as the body or props, on which the federal head rests, and that it cannot remain a moment after they cease. In erecting the federal government, and always in its councils, each state must be known as a sovereign body; but in erecting this government, I conceive, the legislature of the state, by the expressed or implied assent of the people, or the people of the state, under the direction of the government of it, may accede to the federal compact: Nor do I conceive it to be necessarily a part of a confederacy of states, that each have an equal voice in the general councils. A confederated republic being organized, each state must retain powers for managing its internal police, and all delegate to the union power to manage general concerns: The quantity of power the union must possess is one thing, the mode of exercising the powers given, is quite a different consideration; and it is the mode of exercising them, that makes one of the essential distinctions between one entire or consolidated government, and a federal republic; that is, however the government may be organized, if the laws of the union, in most important concerns, as in levying and collecting taxes, raising troops, etc. operate immediately upon the persons and property of individuals, and not on states, extend to organizing the militia, etc. the government, as to its administration, as to making and executing laws, is not federal, but consolidated."
If people running one of many Nation States, such as New Jersey, in a Federation of many competitive Nation States, and the people running that single Despotic Nation State picks the pockets of individuals, taking whatever is worth stealing from everyone, except the criminals running it of course, and their investors who get “tax breaks,” then people could vote with their feet to a less despotic Federated State such as Rhode Island. When everything has been consolidated into one Profitably Monopoly by the criminals who take-over governments, and their investors, then those who are fine with having pockets picked can tell all those who don't like it to leave the one Profitable Monopoly run by the criminal cabal. You don’t like it, terrorist, get out, while I call Homeland Security and rat you out.
This is not really news.

To the citizens of the United States by Thomas Paine
November 15, 1802
"But a faction, acting in disguise, was rising in America; they had lost sight of first principles. They were beginning to contemplate government as a profitable monopoly, and the people as hereditary property. It is, therefore, no wonder that the "Rights of Man" was attacked by that faction, and its author continually abused. But let them go on; give them rope enough and they will put an end to their own insignificance. There is too much common sense and independence in America to be long the dupe of any faction, foreign or domestic.
"But, in the midst of the freedom we enjoy, the licentiousness of the papers called Federal (and I know not why they are called so, for they are in their principles anti-federal and despotic), is a dishonor to the character of the country, and an injury to its reputation and importance abroad. They represent the whole people of America as destitute of public principle and private manners."
The cabal loves investors, and in order to incentivize investors who are perfectly willing to invest in the cabal, there are emoluments and other goodies. These bargains are given out to those who tow the official line, those who don't tow the official line are often found guilty of thought crimes, and either tortured or murdered.
"The validity of the public debt of the United States, authorized by law, including debts incurred for payment of pensions and bounties for services in suppressing insurrection or rebellion, shall not be questioned."
Don't question the cabal's arbitrary power, there are many investors, and you will be first asked to leave, and that is a subtle hint concerning what may come next. There are gang rapists housed on your dime and they would like your fresh meat.
Example 4:
New Constitution Creates A National Government; Will Not Abate Foreign Influence; Dangers Of Civil War And Despotism
Published in the Maryland Gazette and Baltimore Advertiser, March 7, 1788:
“There are but two modes by which men are connected in society, the one which operates on individuals, this always has been, and ought still to be called, national government; the other which binds States and governments together (not corporations, for there is no considerable nation on earth, despotic, monarchical, or republican, that does not contain many subordinate corporations with various constitutions) this last has heretofore been denominated a league or confederacy. The term federalists is therefore improperly applied to themselves, by the friends and supporters of the proposed constitution. This abuse of language does not help the cause; every degree of imposition serves only to irritate, but can never convince. They are national men, and their opponents, or at least a great majority of them, are federal, in the only true and strict sense of the word.”
“Whether national government will be productive of internal peace, is too uncertain to admit of decided opinion. I only hazard a conjecture when I say, that our state disputes, in a confederacy, would be disputes of levity and passion, which would subside before injury. The people being free, government having no right to them, but they to government, they would separate and divide as interest or inclination prompted - as they do at this day, and always have done, in Switzerland. In a national government, unless cautiously and fortunately administered, the disputes will be the deep-rooted differences of interest, where part of the empire must be injured by the operation of general law; and then should the sword of government be once drawn (which Heaven avert) I fear it will not be sheathed, until we have waded through that series of desolation, which France, Spain, and the other great kingdoms of the world have suffered, in order to bring so many separate States into uniformity, of government and law; in which event the legislative power can only be entrusted to one man (as it is with them) who can have no local attachments, partial interests, or private views to gratify.”
So Federal governments afford places where slaves can run away from people running Slave States into places where the concept of liberty, equal footing, and individual sovereignty isn’t just a campaign slogan used to subsidize the slave trade within the profitable monopoly. Those investors in slavery in the slave states can tell the slaves if they don’t love it, then leave.
There are many more examples involving a money monopoly power, aggressive force (criminal force) monopoly power, land monopoly power, just-us monopoly power, and the all too familiar extortion fee monopoly power claimed as a “tax” for your protection of course. The evidence is uncontroversial, clear, unambiguous, and straight to the point.
December 7, 1787
Rhode Island Is Right!
“The abuse which has been thrown upon the state of Rhode Island seems to be greatly unmerited. Popular favor is variable, and those who are now despised and insulted may soon change situations with the present idols of the people. Rhode Island has out done even Pennsylvania in the glorious work of freeing the Negroes in this country, without which the patriotism of some states appears ridiculous. The General Assembly of the state of Rhode Island has prevented the further importation of Negroes, and have made a law by which all blacks born in that state after March, 1784, are absolutely and at once free.”
Melancton Smith
June 20, 1788
“He was pleased that, thus early in debate, the honorable gentleman had himself shown that the intent of the Constitution was not a confederacy, but a reduction of all the states into a consolidated government. He hoped the gentleman would be complaisant enough to exchange names with those who disliked the Constitution, as it appeared from his own concessions, that they were federalists, and those who advocated it were anti-federalists.”
