Does evolution not still play a role? Nature can select for arbitrarily complex behaviors genetically, if it means the survival of the species. I don’t see why the same does not apply here to humans. Like if evolution can select for complex dance routines to ensure that birds mate, it probably will select for a propensity to want to have children. Choosing to not have kids is essentially the same as dying because one was unfit to survive in an environment, evolutionarily speaking. So if most of the people who did not have a strong innate desire to have kids “die”, then the ones who are left are being selected for because they had a stronger innate desire to have kids.

It seems obvious to me that the desire to have kids has at least SOME genetic component, it’s not purely instilled by society, and the “death” (refusal to procreate) of the ones with a weaker drive will mean that the only people left will have a stronger desire to procreate.

I’m not sure though, I would love to hear an argument against this idea from someone with a biology background.
