I would have to object with any assertion that the state should ban anyone from having children. While I would argue that fathers do have an absolute moral obligation to care for their children, I would not seek the vicissitudes of some "lower court" of the state to enforce it.
On this site, Wendy McElroy has shown just how effective and just the state is in dealing with deadbeat dads.
Knowing how creative the state is in using its tools of tyranny, the state will find ways to ban the reproductive efforts of more than just deadbeat dads. And as far as enforcement of such a ban is concerned, I don't want to think about what kind of vile instruments and tactics the state would have in store.
