True there was the time with gold, but I’d suspect an authoritarian country like Russia or China pulling that kind of thing before the US. Plus what would happen if some form of major hack confiscated or stole a bunch of it without something like FDIC protections.
Then again, our currency (due in part to debt/GDP) does feel more precarious than many other countries in some ways.
IMO only.
