None of this is surprising to people who know how bank money actually works. The US congress literally has unlimited nominal credit and practically unlimited useful credit, and it can grant same to any of its creatures.
Of course they could, money is a fiction after all. As long as we all keep walking around believing that fiction, there's no real problem with just inventing more money out of thin air.
The fiction has certain properties when it encounters the real world though, so there are sometimes downstream consequences, but none that could ever totally dissolve the fiction. Only enough people starting to disbelieve in the fiction itself could do that, and people mostly won't do that because money is too useful.
Well if I don't produce that fiction on demand for something called "taxes" I get put in a cage or even killed by men with guns. So I'm pretty motivated to go along with the fiction until the men with guns stop making me.
