Gold is not the only commodity that can be exchanged as 'currency'. Some people will use oil, others might use steel, titanium, etc. Before the dollar, there were other ways of international payments. They haven't been used for years, but they could be used again. The US's economic sanctions and reserve confiscations are the biggest killer for the Dollar. Without the sanctions, the Dollar would probably have been used indefinitely without major problems. The definitive shot to the Dollar's head was the confiscation of Russia's international reserves. If it can happen to Russia today, it could happen to anybody else tomorrow. That makes countries insecure about their wealth. Just like a working man knowing he's possibly going to get fired any time now.
