Why USD is stable and accepted everywhere? Because of countless invasions and wars, especially economic wars, because the bankers are rumored to offset inflation by hand, moving zeros around, because if they fail to keep the ruse going they know that it will be the last one they have, because literally their life, their children, everything they ammased depends on them not letting inflation run away, and because you cannot audit them.
