Gold is not money. Gold is something that some people value but has no value in itself. It’s useful in small quantities for electronics, but other than that it just looks pretty. It has almost no utility. If an apocalypse happens and society fails, gold won’t be worth anything. If people need food, water, shelter to survive, they won’t accept your gold for payment. They can’t eat that. Booze may be a good item that will retain value well, but gold will not.
