I've heard the gold and silver argument, but frankly, I don't see anyone trading food, weapons, medicine, ammo, etc. for gold or silver in a SHTF
scenario.
Gold and silver only have value if everyone SAYS they have value. Otherwise, they are fairly useless metals in such a scenario. Since there is no
collective "someone" yet to decide value, it will all be bartering what people need.
As one said (and I think this is a great point), sharing information is something you can barter with, and yet still keep. How cool is that? Letting
someone upload a file into their device costs you nothing, yet could net you some gear.
