There are better and deeper ways of understanding money. You think fiscally sovereign nations need to borrow their own currency, and that isn't correct. You think government spending necessarily precipitates a currency crisis, and this is not only incorrect but goes against the demonstrated history of the United States from the 40s until today.

It seems like you are conflating the role of private and public debt, which is a very common mistake. Private debt does cause economic crises, public debt is a misnomer - it's generally speaking not even correctly referred to as debt. It's referred to as a debt for historical reasons, its not owed to anyone, for example.

A paper by the CATO institute showed that world hyperinflations have not historically arisen from monetary policy changes. They have more to do with... eh, its complicated. Collapses of industry in wartime, famines, militarily-imposed foreign debts and single-resource economies living beyond their means. The understanding you are demonstrating is called the Quantity Theory of Money and its being more and more called into question. The Theory of Ricardian Equivalence is toast. Not sure if you know that those are the high-falutin names of the theories you are describing as being patent fact.
