Maybe... but humans are forced to acquire resources -- food, shelter, transportation -- by our very nature. Some will resort to crime to get theirs, others will barter, others will do unscrupulous things to get what they need. Silver and gold will most certainly be one way of obtaining things, because whoever takes it in trade will then use it to acquire other things. Humans are economic beings, whether we trade in grain, trade our skills for things, or hunt or fish to provide for themselves and others.

Economics is built into our DNA...trading one thing for another. Westerners are just used to trading currency for their needs and wants, but the history of mankind has a much longer trait of bartering -- and of raiding and stealing -- to get what they want and need.

Be prepared to repel robbers with extreme prejudice, and treat others as you would have them treat you. We'll get through this, but a little silver and gold will make our lives easier than those who did NOT prepare for this moment.
