It is the legal currency, by law all debts are settled in the currency.
If they changed the law so that contracts or debts could be paid in Gold or Crypto then the dollar would be used much less.
Which is why you will never see that happen.
“If they changed the law so that contracts or debts could be paid in Gold or Crypto then the dollar would be used much less.”
