In the United States, abortion is legal in every state by order of the United States Supreme Court in its 1973 Roe v. Wade decision. The logic of the court was a jumble of two issues. The first is the issue of whether the child is a living human being with all the rights that go with that status. The second issue is the right of a woman to do what she wishes with her own body—sometimes characterized as a privacy right—but one which libertarians would more likely consider a property right.

In imposing legalized abortion on the states, the Supreme Court did not see either issue as absolute. Instead, it found that the fetus did have some rights that states could protect, but that the mother’s rights trumped her unborn child’s rights until the baby became “viable” outside the womb. It is also worth noting that the courts have never recognized a women’s right to kill the child, but only her right to end her pregnancy.
Pro-choice libertarians appeal to the same two issues in arguing that no one may prevent a woman from obtaining an abortion. As to the first issue, the question is whether the unborn child is a human person. If the unborn child is not a human being, then it has no rights to protect; no rights even to weigh against the mother’s rights. Denying the humanity of the unborn immediately short-circuits the analysis and ends the debate for those pro-choice libertarians wishing to avoid confronting the non-aggression principle.

Thoughtful pro-choice libertarians, however, will sometimes concede—for argument’s sake—that
Murray Rothbard on the need for a libertarian analysis
Rothbard argued the pro-choice position in his books and articles, notably in his libertarian manifesto, For a New Liberty (1973). He does, however, begin with a fair consideration of what—at that time—was chiefly the position of Catholics:
“For the libertarian, the “Catholic” case against abortion, even if finally rejected as invalid, cannot be dismissed out of hand. For the essence of that case—not really “Catholic” at all in a theological sense—is that abortion destroys a human life and is
