Most gold isn't used in jewelry either, so it didn't derive much value from a fringe use. Ironically we go to huge effort to dig gold out of the ground, purify it, and form it into blocks and coins. Then we dig a new home in the ground, bury the gold in there and put guards outside the door. Someone here pointed out how aliens would be scratching their heads over our behavior if they could see it.
