I hope it goes to zero so I can buy a 100 million ounces or so for, well, the delivery charge I guess.
The reality is, gold shall never be worth zero. Perhaps is a huge solid-gold meteorite landed in Antarctica, essentially tripling or quadrupling the world’s available gold supply, there would be a severe depression of its trading value, but as always, the price of gold is in no wise related to the cost of its production or its intrinsic value as a component of other products. It is purely the demand matched up with those who are willing to sell at a given price.
People shed their ownership of gold because other demands and debts are more pressing than the potential mortgage value of the gold they hold. People buy gold because they simply have too much money on hand and no place to actively invest it.
