In USA, our cash is issued or backed by the Federal Reserve which are the very people creating the problem. In this world, trying to conduct daily household business with gold and silver just isn't going to work. I think you can see the obvious reasons why. Let's say you need something from Walmart. You try to get them to accept gold and they aren't prepared to help you.
Even if they tried, what would the exchange rate so you don't get ripped off?
It isn't a simple matter of thumbing your nose at the enemy now.
