> As for Gold, good luck trying to mine an infinite amount of it.

Biggest barrier to more gold is technology. There's a ton of it in space.

I hadn't thought about that before! Very slick incentive structure there...like, build the tech to go to space and mine it and become enormously wealthy on Earth (ignoring the amount of wealth required to accomplish this).

You don't need to go to space. Gold can be created from other elements. It's just a question of tweaking atoms after all.
