You didn't refute any of his points, political jabs aside. I'm not sure how arbitrarily minting a Trillion dollar coin wouldn't harm confidence in the USD worldwide, it's one of the most blatant examples of debasing a currency I can imagine. I sure as hell don't want to sit on too much cash with ideas like this being seriously considered, or do you think expanding the money supply without expanding the value it represents has no impact on its spending power (or confidence in its spending power)?
Look at any charts of the M1/M2 money supply (that haven't been discontinued) and they seem to strongly indicate we're on a slippery slope towards hyperinflation, that's been the trend for several decades and seems to be rapidly accelerating- At least that's what it looks like to a dumb layman like myself
