When the Apocalypse comes, I hope people don't actually think trading shiny rocks for food is a viable option for feeding yourself! Those shiny rocks aren't intrinsically worth any more than the paper the fiat money is printed on...just like the paper money, they're only valuable because someone thinks they are.

You can't eat, kill food with, or re-populate the world with shiny rocks.

Have a stockpile of food and water, gas for your generator, and someone(s) on hand that you may enjoy being bunkered with.

Fish on...
