The American Revolution was primarily about the initial attempts of the British Empire to implement a gold based fixed exchange rate system. As the United States had no gold, it was unable to trade competitively or pay many British taxes. The American Revolution is proof that you are wrong, as they won the war using only paper money.
One need only read Plato's Laws to understand how money was always recognized as political, and the gold fetish was alien to Civilization. Plato wrote that possession of foreign currency, no matter what the type, should be a capital offense. The Romans too waged war against Carthage in no small part due to their own attempts at using gold for foreign exchange. Gold worship was routinely derided as weakness, and exemplary of a people without honor or social cohesion.
Money is not a store of value. It is a unit of political capital, the value of which is entirely dependent upon the power of the sovereignty that issued it. As soon as that sovereignty no longer can command the people to pay taxes in that currency, nor enforce private debts using civil courts, the money becomes worthless. Gardeners to this day dig up caches of Roman silver coins buried by people who though the Imperial government would return.
