With gold and silver, you have a prayer: Fiat currency...nothing but airWell, there came a point in human history where we needed a medium of exchange that didn't involve carrying 10 big sacks of wheat to market.Money has to have several characteristics.
Fungibility: its individual units must be capable of mutual substitution (i.e., interchangeability)
Durability: able to withstand repeated use
Portability: easily carried and transported
Cognizability: its value must be easily identified
Stability of value: its value should not fluctuate.
Gold has those characteristics. And you can't make more of it. Government can't print it. It is not infallible though. Government can produce coins with less and less gold and more filler. This happened in Athens way back when.
As to whether I think it's good for shtf? I'd rather have the stuff and skills people will eventually give me gold for in the recovery. I could see investing in it once I had everything I needed but that's a never ending list so I don't. It's not a bad investment when compared to the dollar. The dollar has lost 95% of its value in the past 100 or so years. Not a great way to store wealth.
If you are groaning at this point of the post remember you asked .
