Copper is at least comparable, there, and possibly better, and even if gold isn’t valued as a medium of exchange, it’s still going to be more expensive than copper just by virtue of its rarity.
Well, based upon it’s cost and rarity, the price should be around $400/oz or so. The current price is mostly bubble, brought on by speculators. This bubble will burst soon, no doubt, leaving a bunch of amatuers in the dust.
Since gold can be very very thin and still useful, I imagine it’s practical usage would be more common at that price.
So, that’s my WAeG.
