1. ...that "the feds are debasing our currency through their relentless printing"
It is producing a measured, consistent, relatively small 2% rate of inflation over decades and decades. They are of course acting on behalf of an elected body, and ultimately accountable to that body. They're also audited.
2. ...that Tether's relentless, un-audited, 70%-at-most backed printing is fine because the "market trusts it" and "nobody's forcing you to use it."
The market trusts it because number go up, and it's in the interest of exactly zero market participants to show the world the emperor has no clothes.
It's also not fair to say that "nobody's forced to use it" when everyone is forced to use it. In 2018, 80% of all crypto exchange transactions were conducted in Tether. That makes USD transactions by far the minority. Since arbitrage bots keep the prices in sync, and the majority is USDT, even the USD exchanges follow the USDT prices so long as there exists sufficient liquidity to balance the books. [1]
