It's not at all obvious to me that, even if monetary cost per child approached zero, people would have all the children it was biologically feasible to have, specifically because of the bottleneck on parental attention (but also because many people don't want children, or want a smaller number for some non-money-related reason). I don't think a majority of choices about family size have much to do with money at all.

I didn't say that. I merely think that the (world average) birthrates would be well above sustainment level. Three children per family on average would be more than enough for a population explosion.

Unfortunately, if we have a future of many generations of biological humanity without significant resource constraints, memetic selection will make sure most people do want many children. This must happen as long as some people want many children and can teach most of their children to want the same.
