So Sorry, I forgot the second point. You wrote: Second, what if I set myself up as a coin dealer, pay myself in legal tender coins?
Because in order to do that, you, or somebody, has to first purchace the coins with which you are paid.
Let's bring it down a notch. Consider why it is that AGEagles are not reportable. They are not reportable because they are nothing more than an exchange of one currency for another. Much like trading in two tens for a twenty.
Sure, this gold-guilded twenty may someday be worth more than would the two tens, but on average, they will be worth exactly two tens, or perhaps only slightly more. You may get lucky and end up holding a couple of million worth of gold when a run on the market happens. Then again you may get unlucky and end up holding a couple of million worth of gold when a dump comes. In the end it evens out so gracefully that the U.S. Gov, IRS et al, does not bother to make any real special rules concerning its trade.
Note that for other gold currency, they do make special rules. Usually when the currency in question is not tied dollar-for-dollar to the Fed Note.
