The problem right now is that central banks have not normalized their balance sheet since 2009. They're trying, but it's not even close. If we had another crisis tomorrow, and you had to do QE4 and QE5, how could you do that when you're already at $4 trillion? They might have to turn to the IMF or SDR or to Gold. Then, if you go back to the gold standard, you have to get the price right. People say there's not enough gold to support a gold standard. That's nonsense. There's always enough gold, it's just a question of price.
