Can we all agree that the amount of humans which the Earth's (mass/surface area/volume/energy/environment/resources/what-have-you) can support is finite? Can we also agree that the ideal number of humans on Earth is somewhere between 0 and this finite limit?
In this case, I would simply argue that the ideal amount is somewhat lower than the amount of humans which would necessitate covering the entire Earth's landmass and oceans with a planet-sized city, obliterating all natural landforms and all species except those found in factory farms and zoos.
I guess what I am trying to say is, if we consider overpopulation not to be a problem, then we must believe that humans are wise enough to stop multiplying before Earth becomes a monoculture. This is the argument that I find hard to believe.
