One of the most common justifications I hear for abortion is "a woman should have control over her body."
If humans reproduced oviparously, would that change the debate? Let's say a woman conceives a child, and then immediately lays an egg. The egg would still need incubation and maintenance, though this could be performed by any party, not just the mother. After nine months of development, the egg would hatch into a baby human.
Would a woman be justified in crushing this egg? This mimics the abortion debate, except that in this case the fetus cannot be addressed as part of the woman's body. Would that invalidate any abortion arguments?
