Who said anything about bringing the gold standard back?

I suggest that no central bank holds commodities of all kinds. You are mistaken. You don’t think it’s weird that the Fed has gold in a Manhattan vault?

Why would they, if, as you say, gold has no real value?

Gold is not just another commodity like all others. Commodities are not at all like each other. You can not substitute corn for oil without great expense. You can’t swap in copper for soybeans. They are unlike each other in various ways.

Gold, for instance, is unlike any other metal as a matter of the physical inherent qualities it and it alone possesses. Some metals have some of the same or similar qualities, but none have them all.

These qualities (as I expound on in another comment in this thread) are what make gold ideally suited as a monetary asset.

As to the problem of shipping gold overseas, that can be remedied by 3rd party vaults. You can have digital gold accounts — and in fact these already exist. The issue you raise is made obsolete by the technology to instantaneously transfer ownership of allocated gold from one person or government or business to another.

But I’m not an advocate of a gold standard. I think we should have a free market in money, not one enforced at the barrel of a gun like we have now.
