Ownership is a law-dependent condition and should, in theory, be subject to social standards of behavior. However, perhaps because the U.S. legal system is very materialistic, property rights have trumped individual rights and are now perceived as a guarantor of autonomy. Since individuals have no personal rights that are protected, they should at least be able to do what they want with their property. And, by the way, that includes their children. The objection to the premature termination of pregnancies is based on the presumed male parental property right in the fetus. The absence of guaranteed personal rights is actually considered a boon in some quarters. If there is no personal autonomy, authority has an easier row to hoe.
