Sure. And we're over-supplied with breathing air to the point that nobody bothers to store it in bottles for a low-air day. I don't think we can reach saturation supply of everything we might possibly want because we're naturally competitive, explorative and status-seeking and will just invent new things to want, even if they're zero sum. Those things will probably be able to be bought with money.
