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:
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
- the woman has publicly announced her abandonment of the right to custody of the fetus, and
- no one else has "homesteaded" that right by offering to care for the fetus.
Likewise, Block proposes that medical experimenters can treat the embryos they have in their possession as laboratory "animals", as is their desire, contingent on only one stipulation: that no one else wishes to raise these very young infants on their own. If there are adoptive parents who wish to homestead the right to care for the children, their rights trump those of the creators of the fertilized egg since the former wishes to protect the child from harm, while the latter does not. Thus Block offers an alternative to the standard choice between the pro-life and pro-choice positions on stem cell research.
Advances in technology
Evictionists believe that advances in technology will continue to improve the medical ability to preserve a living fetus after removal from its mother. This future technology is hoped to save the lives of evicted fetuses at increasingly younger ages whereas aborted fetuses would continue to die at any age.
During the past several decades, neonatal care has improved with advances in medical science, and therefore the limit of viability has moved earlier. The lower limit of viability is approximately five months gestational age, and usually later.
