"it's beaten into our brains from a very young age " I think it's instinctive in a far far deeper sense than just human social conditioning. Having 2.2 surviving children is basically an absolute minimum for survival of the species, ergo, there are very, very deep evolutionary aspects at play here. If humans didn't have these normative instincts, maybe you and I would probably never have come to fruition. One could easily argue that 'having children' is essentially normative - as normal as being born and dying. And that 'not having children' is 'a choice that is made' type thing.
