I didn't think "the universe has a finite capacity" to be such a controversial idea. Look, if you use land for farming then you can't use it for something else, right? And the Earth has a finite surface, right? So once all arable land has been farmed and all other land has been allocated for other uses, then necessarily land allocation will become a zero sum game. If wealth can just be created ex nihilo then human population should be able to grow without bounds, no? The pie is a lie, after all. We can just bake more pies. I don't see how that's possible when both space and food production capacity are bounded.
