Yes, that does sound crazy

But on the other hand, this article from 2006 did point out a few little problems that have sort of been ignored:

I mean, if we can accept for a moment my
premise that there’s no way of curing the fiscal problem shy of a bankruptcy—
and that there’s no way the government is going to renege on
its debt—I’m sure it’ll do what has been politically expedient in the past:
You rev up the printing presses and pay off the debt with the money
that you print—even as that money becomes worthless. The thing is,
with the dollar, we are dealing with the world’s reserve currency. So we
are talking about a global crisis of unprecedented proportions, probably
one that would lead to the collapse of the current currency system.
You’d probably have to have an international conference to reconstitute
the global currency system and somehow build confidence in the public
that the new system will work and that it’s stable, so that we are not
put in the same position as the poor people of Germany, after WWI,
because that is the type of hyperinflation that could evolve here. So the
cures will have to be remarkable. They will have to convince people
that things have changed. As crazy as it sounds, I think the only thing
they will be able to do is to go back on some kind of gold standard.
