I don't agree that any of your examples quite work. Imprisonment, execution and corporal punishment follow some behaviour that we agree is wrong, unlike pregnancy. (Personally I disagree with capital punishment and most forms of corporal punishment anyway.) And as for child support and taxes, I think there's a relevant distinction between bodily autonomy and financial autonomy.

The retributive aspect is not important to the many people who hold the deterrence view of punishment, and no one holds that, say, the draft or taxation is punishment of people for wrong behavior.

Why would you think that? Financial wealth for most people is just their labor in another form, and labor is just their bodily autonomy. A job is a way of trading...
A few years ago, I wrote a little dialogue I imagined between 2 materialists, one of whom was for and one against abortion, centering on the personal identity question. I recently cleaned it up and added a number of references for the biological claims.

Early feedback from #lesswrong is that it's a 'nicely enjoyable read' and 'quite good'. I hope everyone likes it, even if it doesn't exactly break new philosophical ground.
