Sure, that end is noble, but the ends don't always justify the means.
Obviously these child support laws are in need of reform.
At what point do they attain human rights? At conception? At "birth" from an artificial womb? What defines "human" in "human rights"? (Can they knock out a few genes and make a sentient creature that is capable of suffering but not human? We have sentient non-humans suffering in factory farms already.) How will we prevent people/corporations/governments/religions from just deciding to create a bunch of people? What does regulation look like in this inevitable future?
This is hardly a new issue
In and of itself, no. I'm saying there's issues with some particular ways of doing so.
