Currency is a product of culture. There is no homogeneous culture. You can't design a perfect experiment here. It's not an accident, that's not what survivor bias is, it's just that it's also not "gold is valuable because god himself ordained it and therefor it always will be until the end of all time". Gold is valuable because we decided it's valuable. Other things have been used as currency, but people simply decided that gold is a good thing to use as a basis of an economy. The fact that our current culture says gold is valuable because in the past it had been repeatedly valuable and therefor it will be valuable in the future is an illogical statement because of the part at the end. You can't predict the future. You can't actually know that the train of thought that made gold valuable in the past/present will keep running in the future. Maybe we move to away from capitalism and skills are more useful. Maybe a giant meteor full of gold is found and it becomes less valuable than silver or platinum or uranium or any other semi-rare stable element. The point is, trade goods have their value tied up in need instead of perception and currencies are the opposite. Hoarding gold has shown to work in the past when. This has less barring on it's value in 100 years than you're trying to say.
