It's an issue of use versus abuse. All hormonal agents are potentially abortifacients. They work by suppressing ovulation, thickening cervical mucus, and preventing implantation. They have been wildly popular, including among Catholics and Protestants, for decades. They have dangerous and unpleasant side effects, but are not expensive. There is no legit need for insurance coverage.
I wonder whether in-patient only abortions would catalyze the necessary, unpopular, agonizing discussions. No, we like our solutions quick, dirty, free, and private. It's our "right".
