From a libertarian perspective, if someone is dependent on you for food and shelter, what compels you to continue to provide those? There's no moral burden to help someone else, as they have no claim over your resources. Choosing not to supply a fetus with your nutrients and hormones - the result of hard work, fruits of your labour - is totally in line with my understanding of libertarianism.

So you must be against child support and child negligence laws right? I for one cannot wait for our new libertarian utopia stepping over the bodies of neglected, abused, and traumatized children. It's scary what some people fantasize about.
