The demand for dollars is what gives it its value. The dollar is the standard for world trade. All the countries have to use it to trade with each other so our government requires them hold a certain amount for that purpose.

If the governments decide to use a different currency and give back ours their is no demand.

It like somebody puts out a teleport machine so the demand for cars disappears and nobody wants them. They just pile up in scrap yards.

Dollar= car BRICS= teleportation.
