The gold "price" prior to 1971 was a pegging set by central banks, only adjusted slightly every couple of years. A "free price-fluctuating world market for gold" as we today know it only exists since the 70s. (Some argue we're still under central bank-managed price pegging, just "smarter" but let's not go there...) Rendering your point pretty useless.
