Ok. I agree with you on the empirical assertions (I actually suspect that 10-month-olds also lack blicket). But my moral theory gives significant weight to blicket-potential (because blicket is that awesome), while your system does not appear to do so. Why not?

You mentioned to someone that the current system of being forced to provide for a child or place the child in foster care is suboptimal. I assume a substantial part of that position is that foster care is terrible (i.e. unlikely to produce high-functioning adults).

I agree that one solution to this problem is to end the parental obligation (i.e. allow infanticide). This solution has the benefit of being very inexpensive. But why do you think that solution is better than the alternative solution of fixing foster care (and low quality child-rearing practice generally) so that it is likely to produce high-quality adults?
