So if the sky falls and civilization ends how are you going to eat gold & silver? Anyone have any good recipies?
Gold and silver will keep their value if it is only their country that collapses and the others are still stable. A complete collapse of all countries (which is WAY more unlikely scenario) would probably mean that gold and silver also suffer loss of value.
Also, there is a Finnish short story where a guy has been preparing for the collapse of society by hoarding things of value.
Gold? Silver? No he argues that those aren't any safer than currencies since none of those have any actual use, only the value that people agree for them to have.
He bets on something that people will always need no matter how much the world changes: Booze!
The story is called "Viinankätkijä" (Booze stasher/hider) and the guy spends the extra money he has on booze and then hides it in tiny stashes all over Finland.
