The inflationists' dream

"Clearly, the inflationists' dream is some sort of world paper money, manipulated by a world government and Central Bank, inflating everywhere at a common rate. This dream still lies in the dim future, however; we are still far from world government, and a national currency problems have so far been too diverse and conflicting to permit meshing into a single unit. Yet, the world has moved steadily in this direction" What Has Government Done to Our Money?, Murray N. Rothbard em 1980
