It sounds like the logic of pro-lifers who only care about protecting you while you're in the womb, but then throw you out to die once you're born. We should be making sure future generations have a world left to occupy before spawning them into this hellhole. If you just ensure more people are born, then expect the details to sort themselves out, then you're putting the cart before the horse. More people make the world worse as often as they make it better, and the more of them you have, the greater the odds that things default to competition over cooperation.
IMO, the ability of population growth to quickly scale upwards or downwards with the prosperity of a culture is essential to keep them from exceeding their own carry cap and dying off quickly, or else needing to invade other cultures to sustain themselves. Especially in such an already flimsy paradigm as the western one, which is actually highly unstable despite many people's impression that it's an indomitable juggernaut.
