What about devaluing the dollar. Other countries have done it. Say instead of inflation, we have deflation, (stagflation) which is what the majority of Americans have experienced over the past 25 years. In a similar scenario, the Fed would raise interest rates to where no one could borrow money and wages and income would remain stagnate (remember the three years under Obama where there was no increase in Social Security benefits while real inflation kept going up?), people would run up credit card debt and go bankrupt paying 40% interest. That's when you devalue the dollar. The Japanese, faced with the same predicament, did it and saved the Yen and Argentina did it to save the Pesos, which kinda worked. Besides, what currency would replace the Dollar? Euros, Pounds, Yuan's, Rupees? The IMF would have to pick one. Crypto is to risky and volatile. We've saved the dollar on numerous occasions, 1982, when the government really did almost go broke, '87 and most recently in 2008 when we came within minutes of the whole shebang collapsing.
