Ah absolutely, the much more tangible short-term example of “guys with guns” is (admittedly ever more militarized) domestic law enforcement.
But the implied threat towards anyone who say, started dumping US sovereign debt, or transacting petroleum in EUR, or whatever is very real. Countries have been liberated for less.
Thank you for the links. I was unaware that the PRC’s Treasury holdings had been pared back so much.
I do think it’s interesting to note that both of the examples you used are the only two countries that the US military wouldn’t like to try its hand against. And there is a broader point there: my original point becomes less relevant the further that global US hegemony slips.
I admit it is mighty convenient for the US to have the dollar as the reserve currency, but really, you are stretching your point, people outside US not accepting US dollars don't have violent threats looming over them.
