You say this like the resources needed to raise a child are extracted from society as a whole. But they aren't in general, and they certainly don't need to be. They come primarily from whoever is having the child. That person is indeed free to allocate their resources as they see fit, and that includes using them to raise a child. Once the child is grown, they can contribute to society. The only burden that is ever placed on society as a whole is through entitlement programs that redirect resources to children or parents, but society doesn't need to offer such benefits. It may choose to, but it cannot fairly use that choice to deprive an individual of the choice of how they allocate their own resources.
That's an interesting argument.
1) Do you assert that it would be moral for society to refuse to recognize the human rights of some of its members?
2) Do you assert that recognizing the human rights of a member of society doesn't impose a burden on society?
It seems clear to me that every time you have a child, society as a whole receives the burden associated with that child's rights, whatever they may be. But if you say yes to either #1 or #2, then this point may be worth discussing further rather than simply assuming that it's true.
