Listen, if we get to the point where gold is worthless and food/water/guns are main things, we're all screwed. It's not even really worth preparing for that scenario because at best you can only buy yourself a couple miserable months before you get ambushed, big whoop. If you go back to the German hyperinflation, they had to rebase on gold and silver. It's not something you should put a lot of money into, but it's one of those insurance policy things that a very small percentage of your total net worth should be allocated to as there are times when gold and silver will outperform the stock market (like the 70's inflation period). It's not there for end of the world scenarios, it's there for times of inflation.
