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.
To clarify, when people colloquially refer to “the collapse of society” they don’t mean that all forms of society would cease to exist, but refer to the failure of the nation state, or possibly the international order, and the long supply chains that go with it. Etc.
So society at various scales would still exist, in overlapping ways and jurisdictions. Basic units like neighbourhoods and firefighters and towns and regions would be organizing based on the old rules and adapting. People organize well in the absence of warlords, so that and extinction events are the threats to trade.
The value of trade goods might be indeterminate if a comet wipes nearly all of us out. Otherwise, many people love to dicker and argue about the value of things, so I’m pretty confident about rare raw materials like gold having both utility value and a reasonably inflated exchange value in a prolonged regional or international crisis.
