OK, I may have misphrased myself; or you didn't see the posts I was replying to, because that's not what I meant at all. I was replying, if you scroll up, to someone who was talking about how a "silver standard" simulated a "medieval economy". I meant that it made no economical difference which metal you pick. Obviously pricing everything in rabbit poo would make an aesthetic difference. But there's no medieval economy here.
Do you realize the kind of inflation you'd have in a rabbit poo based economy ;D
