Silver has lots of uses in manufacturing, medicines and electrical workings. It is easily worked by hand and alloyed with other metals. It is portable (to a degree) and will be again the medium of excgange if the wheels come off society. You may not always have trade goods that interest another party.But who's gonna be trading in silver? Where will accept it? I'd rather trade in goods personally. As would a lot of people I know. I'm not knocking silver stockpiling, just trying to understand it.
