I agree with this.
Really, the only libertarian pro-choice arguments that pass any degree of logic are the evictionist arguments from guys like Block and I think Rothbard as well. The debates to try to make the fetus as not being a human being with rights are ridiculous and reek of the same "logic" that animal rights advocates use. The extreme animal rights advocates are certainly not libertarian.
I make it from a property rights argument. Your body is private property. Even if you believe the fetus is a life, if the woman doesn't want it and it the fetus doesn't leave (which it obv. can't) then she has the right to forcibly remove it. The fetus' rights stop where her rights begin and it is violating her property rights in the same way an intruder would be violating your rights if they broke into your home.
Although I flip back and forth on this issue.
