Milei opposes abortion rights, and has publicly affirmed a staunch anti-abortion stance, saying that abortion violates the non-aggression principle; he sees it as a property conflict or issue of ownership, and drew comparisons between abortion and theft.

Milei spoke in favor of a legal organ trade, seeing as a way to reduce waiting lists for organ transplants, and said that there could be market mechanisms to encourage organ donors. He said: “If women can have control over their bodies, why not everybody else?” In a June 2022 interview, when asked about his stance on the sale of children, Milei initially said that “it depends”.
