Wtf are you even talking about. Do you feel like some people should be starved, homeless and sick because else they would "breed like rabbits"? What a deranged view to hold.
I said human wants are limitless. You said no they're not. I said yes they are, giving the example of population growth as a way that aggregate demand increases even if some people are completely satisfied. This is ECON 101 and a small amount of biology. That's what I am talking about. Notice "need" and "want" are 2 distinct words and you are reading past the difference.
Demographic transition in one culture does not imply universal demographic transition across the species. Because those who haven't yet transitioned will control population growth rates.
Now why did I say this? Because you opened by presuming that socialism would solve human wants. Which is nonsense. Nothing solves human wants.
Demographic transition is absolutely a universal phenomenon, no country has ever been observed taking another path.
I reiterate, the need for food, housing and medicine is not unlimited. The population is not infinite and humans have a limited need of these things. Do the math: finite×finite=finite
"Nothing solves human wants": what about prices? It seems like it does. It's a flawed solution that leaves some with nothing, but it does solve it. Now, what if we distributed the basic utilities on an as-needed basis. That too would solve "human wants" on those things, and would ideally leave none lacking.
Please don't quote "econ 101 and basic biology" at me without actually engaging with what I'm saying. You're ignoring material reality and using abstract nonsense to deter from the subject.
If you really believe this shit, read https://en.wikipedia.org/wiki/Demographic_transition
Humans are very much unlike microorganisms. Populations don't explode when their needs are met, quite the contrary.
