Because abortion is not about protecting life, not in the minds of Americans who oppose it. It is about imposing controls on women's sexuality. If a woman is as free as a man to have sex when she desires, we will turn into a veritable Sodom and Gomorrah. Among older (50 and up) Americans, women are expected to be chaste, pure, only have sex when married, and get only a small bit of joy from it. Women who enjoy sex are sluts, in the minds of these forced-birthers. If women are forced to live with the consequences of their slutty behaviors, they'll stop doing that.
