I was given some gold as a gift and tried to sell it, they take a cut off the top and there are no laws regulating how much a coin shop can charge for exchanging (unlike securities). People don't realize it is easy to buy gold, but a LOT harder to sell it. Especially if there is no provenance like an ingot with a hologram vs. a golden eagle. But like a lower poster says, there is a lot in between, but do you remember COVID and how insane people went over toilet paper? To quote william burroughs: "Man is a bad animal".

Because there are a lot of scenarios between total apocalypse and status quo. The USD may collapse partially compared to other currencies and common assets like BTC, gold, silver without me having to defend my home from raiders and trading whiskey for ammunition.

What is an example where gold temporarily replaced a country's currency and it did't go full mad-max? I don't think you have any evidence to back up your claims, but I can just point to COVID and toilet paper to show how slippery the slope can be (replace toilet paper with "food" and play that out in your head). I didn't even mention Zimbabwe (which more closely resembles the Trump regimes blatant corruption) where wheelbarrows of bills couldn't buy bread.
