Well if you are ignorant of medical technology that's fine, at least you asked. C-sections for one. Now-a-days, with current technology practices babies can survive at 6-7 months, and I wouldn't be surprised if in the future they could incubate the fetus (so at any time the woman could evict the baby). The mother and doctor still would take the risk if the child was harmed in the process, so it isn't like it's a scott-free type of thing.
Now, where it gets hairy is the question whether the mother of the baby has a responsibility for the babies welfare. That's a tangential subject and probably one that would result in a lot more....let's just say passionate argument. I also presume such an argument would be frought with fallacies and emotions so for the average person it would devolve quite quickly, since even a lot of so-called libertarians can't grasp that a right is by itself neither right or wrong, but is. Right or wrong is then up to your personal beliefs (for instance take freedom of speech. It's my right to tell everyone I ever meet to fuck off douche, but that doesn't mean it's right). E.g., the mother is not responsible for the child's welfare, but I would say it's wrong not to do so.
Yeah, probably not the right avenue for the speech (non-academic setting) as well as there are a lot other important things going on that dwarf abortion.
