Ok genius, what's going to replace it then? Will we buy oil using cow hides? Will every port terminal have an integrated precious metals department that does a gold based COD for every container? Or maybe we'll move to Euros, a currency backed by a bunch of bickering states that can't settle on a clear set of economic policies? Or maybe we'll move to the Yuan, and put our faith in a country that seems to give away endless amounts of free money to state owned enterprises and has zero respect for fair trade policy?
