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.
Also a in a societal collapse markets will reestablish themselves relatively quickly so if you have a trade good like gold, copper, or silver you could probably use it as a solid liquid asset. Mind you I’d say a 1-2 year minimum for markets to reestablish themselves so you have to survive that first. Also you will be at the mercy of the merchants and tradesmen regardless.
