> they just borrow lots of money and then default on it.

I don't think anyone is claiming that the US government is going to do a straight default on their debts. If anything troubles them they will use monetary policy.

> In the case of shiny metal money, that’s usually deflationary, but not always: see the Spanish Price Revolution of the 15th Century https://en.m.wikipedia.org/wiki/Price_revolution

I'm not going to see anything useful to me an economic event from 500 years ago in a language I don't speak, enmeshed in a foreign legal system, totally different technological and social conditions and potentially questionable record keeping with uncertain customs around law enforcement.

Even the frame there is incomparable; Wikipedia is quoting 1–1.5% inflation as 'high'. I wish that was considered high these days, I think low inflation leads to good results.

Honestly that just looks like supply and demand. Lots of new metal -> price changes. Hardly a problem.
