I do not agree with evictionism in its entirety. I do not believe it is compatible with libertarian philosophy, and is a bad compromise.
I do however agree that the rights of the woman to her body (property) must be balanced against those of the fetus. I also believe that murder and torture are worse transgressions of an individual's rights than trespassing.
So an unwanted fetus is trespassing on the woman's property. The woman that aborts the fetus is sometimes causing great harm/pain/torture to the fetus, and then killing it.
The second part is the point that I believe evictionism fails to address adequately.
To me then, the key question becomes: At what point should the fetus be considered a human being, and be afforded all the rights that libertarians generally agree upon?
My answer to this question, is that the fetus should be considered a human being when its brain and nervous system have developed to the point where it can feel pain. I do not know what age this is. It may even be different for each fetus. So I would advocate that scientists and doctors define that policy, which may not be one-size-fits-all.
Anyway, to my mind, before this cut-off point, the woman should have every right to rid her body of the unwanted organism (parasite) via day after pill, surgical procedure, or whatever available technology. After the cut-off, it is legally a feeling human being, and the woman should be held accountable for murder (lowest degree) if she aborts it.
It is the woman's responsibility then to monitor her body after engaging in intercourse, so that she becomes aware of the pregnancy before the cut-off point. Failure to do so would be considered negligence, and therefore not a justification for committing murder after the cut-off point.
This assumes of course, that technology is available that can inform the woman she is pregnant before the cut-off point is reached. I am not a doctor and the cut-off point is undefined in this argument, but I do believe that today's technology is sufficient and affordable for most women.
I actually believe that the same notions about "can feel pain" can actually be applied towards our treatment of animals also. I think that is a related, but tangential discussion, and any comprehensive libertarian answer regarding abortion should address both from the same root principles.
thoughts?
I actually heard Walter's speeches, and wanted to talk to him about my approach, but other great speakers were lined up after him.
