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.
Even at the basest level of society that we might fall back to, there will be a need for stores of great value in order to make larger trades. You can’t effectively trade large scale without it. Which might not be relevant right after a full system failure, but definitely afterwards.
