When the U.S. left the gold standard it was giant fuck you to all the countries who held dollars and could no longer exchange them for gold. The U.S. maintains and exercises military power globally in part to protect the dominance of the dollar.
Note also that state/local taxes in the U.S. are completely different from federal because they can't just make dollars and can only spend dollars received through taxes (which are not deleted in that case) or received from federal spending (or in some cases through the state itself doing business in the market).
