But does it really defeat the hypothesis? I'm not sure. It seems to me that supposing buyers who are willing to throw dollars around as if they were worthless and thus drive up the dollar price of gold, arbitrage will spread the price increase to other currencies, especially if the dollar retains some element of a reserve currency. With a minor currency it would be more likely that the effect would be isolated to that currency.
I don’t mind gold going up, I sure hope that US dollar supremacy stays strong. If the BRICs ever make a serious dent on the USD as the #1 reserve currency, your standard of living will go down too.
