The vast majority of the public with destroyed pension plans, starving seniors (SS destroyed), hyperinflation, and inability to buy hard goods from other nations who want the US dollars as much as the Zimbabwae one.  Yeah I am sure they are going to say "hey you guys who royally fucked up everything and destroyed our standard of living please do it again".

No the US would be like any other failed currency state.  People would hoard ALTERNATIVE currencies and shun anything that has to do with the state.  For some it might be Bitcoins, for others it might be Euros, Canadian dollars, gold, etc.
