I know people out there who have invested a lot in gold under the belief that in the event of like complete societal collapse or hyperinflation, they could use it for purchasing.
I have the hunch it’s a scam, but I haven’t learned enough monetary theory, business, or economics to understand why.
It isn’t a scam. It is an asset like buying land in the middle of nowhere. It will in general match inflation but underperform most other investments. In the very long term I would expect that with global population stabilizing and declining, the value of gold will also stabilize and decline.
