Some mammals take care of their young.
Some mammals abandon their young, typically the runt starves.
Some mammals (even rabbits) eat their young.
All of these behaviors are predicated on instinct.
I believe our legal AXIOMS should (naturally and ideally) conform to,
(1) Protect yourself.
A citizen's body is sacrosanct.
A citizen's personal information is sacrosanct.
(2) Protect your close friends and family.
Activities and transactions between close friends and family members is sacrosanct.
The information you share with your close friends and family members is sacrosanct.
(3) Protect your territory.
A citizen's personal real-estate-property is sacrosanct.
The information concerning activities and or other property that may or may not be located should only be public insofar as those activities and or other property can be observed from outside a citizen's real-estate-property line.
That being said, I also strongly believe in following the letter of the law-of-the-land.
I don't have many ways in which to counter your statements (not that I would since I cant argue against the fact that you believe everything you just listed.) That being said, I'll state this:
I argue that all individuals are sovereign, and that the laws of the lands are currently subverting them. Instead of letting law reflect a moral economy, common law especially deludes groups into Hobbesian traps, creating a fundamentally adversarial environment. And in glorious contradiction, the true nature of man as Hobbes would argue, is not excluded from those who'd presume to govern. In the context of this discussion, I do not argue that woman has a right to her person because the law legislates it, but because she's a sovereign individual. More to the point, in any interaction between individuals, to maximize--and I'm using this term particularly--any transaction conducted between them, their self-interest ought to/must be respected. Self-interest is the starting point to any interaction.
Furthermore, I'm not going to argue that the zygote/embryo/fetus isn't a life, not only because I firmly believe that is not the case, but also it isn't necessary to sustain consistently a pro-choice position. That is, whether one concedes that the zygote/embryo/fetus is a life, it doesn't have a right to its mother's womb. Gestation is its mother's gift, not the unborn child's entitlement. By the same token, I would also argue that rearing is its mother's and/or father's gift, not the infant/child/adolescent's entitlement. While some would argue that the termination of pregnancy is tantamount to murder, I would argue otherwise. While in some cases, I'd argue it is, in the case where it's merely expelled, the death of the fetus isn't a result of its mother's malice aforethought, but the undeveloped physiology of the zygote/embryo/fetus. The fetus's incapacity to survive outside of its mother's womb is an unfortunate consequence of nature.
The right to one's person is derivative of individual sovereignty; to undermine any tenet of said principle is tantamount to undermining the principle in its entirety. So despite my personal objection to abortion itself, my sustenance of the pro-choice position is a necessity to my adherence to individual sovereignty.
