Gold hasn't always or everywhere been real money, I've personally worked on an archeology site where I sifted out a tiny shell bead with an even tinier hole punched in it so it could attached to a string like ancient Chinese coins and so on.
I once read a claim that J.P. Morgan said something like money is only worth the character of the person who wields it.
I feel more like interactions with other people are more precious than precious metals.
If the dollar hyperinflates, some people will go into bunkers. I'd maybe starve or hide... I don't have a plan, I'm way behind on stuff as it is.
