Well, I agree that the combination of printing money with no taxation isn't going to work due to inflation. I just didn't understand the statement that a currency's value "derives largely from the ability to pay [income] taxes with them". That statement by itself is historically false, as the gold-backed currency shows. It still makes no sense to me even without gold-backing. As long as the money supply is kept relatively stable, all you need is for a few government services to operate exclusively in USD (e.g. welfare, where funds are raised via land tax or carbon tax for example), and for a reasonable amount of trust in the government, and to perhaps kickstart the group delusion of trust with initial gold-backing, and you're all set. I can make sense of the statement strictly in the context of money printing, where you need the offsetting deflationary impact from taxation (not necessarily income taxation), but that meaning wasn't so clear from the original statement that I was responding to.
