What is "evictionism"

Evictionism is a moral theory advanced by Walter Block and Roy Whitehead on a proposed libertarian view of abortion based on property rights. This theory is built upon the earlier work of philosopher Murray Rothbard who 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. Evictionists view a mother's womb as her property and an unwanted fetus as a "trespasser or parasite", even while lacking the will to act. They argue that a mother has the right to evict a fetus from her body since she has no obligation to care for a trespasser. The authors' hope is that bystanders will " homestead" the right to care for evicted fetuses and reduce the number of human deaths. They argue that life begins at conception and state that the act of abortion must be conceptually separated into the acts of:

1. the eviction of the fetus from the womb, and
2. the killing of the fetus.

Building on the libertarian stand against trespass and murder, Block supports a right to the first act (eviction), but not the second act (murder).

Walter Block believes the woman always has a right to evict but may only legally abort if the fetus is not viable outside the womb, or

1. the woman has publicly announced her abandonment of the right to custody of the fetus, and
2. no one else has " homesteaded" that right by offering to care for the fetus.
