Anarcho-capitalist philosopher and Austrian school economist Murray Rothbard wrote that "no being has a right to live, unbidden, as a parasite within or upon some person's body" and that therefore the woman is entitled to eject the fetus from her body at any time. However, explaining the right of the woman to "eject the fetus from her body", Rothbard also wrote that "every baby as soon as it is born and is therefore no longer contained within his mother's body possesses the right of self-ownership by virtue of being a separate entity and a potential adult. It must therefore be illegal and a violation of the child's rights for a parent to aggress against his person by mutilating, torturing, murdering him, etc." Rothbard also opposed all federal interference with the right of local governments to fashion their own laws, so he opposed the Supreme Court's "Roe v. Wade" decision. He believed that states should be able to author their own abortion policies. He also opposed taxpayer funding for abortion clinics, writing "it is peculiarly monstrous to force those who abhor abortion as murder to pay for such murders".
