That is to say, its intrinsic value includes electrical conductive properties and capacity for use in electrolytic plating. I am ignorant, what are some other intrinsically useful properties of Gold (and Diamonds?)
The problem with Gold is also it's virtue: it's rare. Rarity is good in that it implies value. But let's say you're the American economy and you're growing 2% this year. Should your money supply be governed by how much of it you can dig out of the ground? That is, for example, when South African gold mines were discovered the money supply internationally radically increased, despite having no relationship to economic output. That ends up not working out very well.
Bitcoin though could be thought of more like gold and diamonds not because those things are good to think of as currencies -- they really are not good currencies at all-- but because their all commodities with limited supplies that have markets that move on vagaries with little relationship to any economic necessity or output.
