Look at history. Germany abandoned the gold standard in 1914. Their hyperinflation period started in 1922 as they printed to pay debts, by November 1923 the exchange rate for USD to Mark went to 1/4,000,000,000,000.

Yea they also just had lost a world war and werent the global reserve currency
The US is funding wars on multiple continents today. Almost half of global GDP is forming a Bloc based on hard assets (gold) and at the same time they have stopped buying US debt. Your faith in the reserve currency is unmatched. Enjoy the ride.
