No, the reason they have "value" is by common consent. The scarcity issue determines what options are available to manage the money supply, but gold/silver is still only valuable to me if someone else wants it. If I were starving on an island, I'd much rather have a sandwich than a bar of gold. Gold is worthless without someone else around who wants it, just like fiat money.
