Dollars are currently only in demand for short-term use in transactions. Most of the world still relies on dollars for transactions, because that is what all the banking and payment infrastructure uses.

But no one wants to hold them because they devalue and will continue to do so at an accelerating rate. It's a game of hot potato where everyone is forced to hold equities, commodities or other assets by default in order to preserve their wealth, and then convert to dollars to transact. The days of savings accounts are over, and everyone should think of their checking account as something that they pay negative real interest on for the privilege of being able to transact with the rest of the world.

Meanwhile, the big players in the current financial system are trying to figure out how to continue playing the current game without resetting everyone's progress. They don't want to lose their hard won position to pay for bad decisions by American voters. It's a coordination problem, and the shelling point looks like it is still gold, same as it has been for thousands of years.
