Here is a lesson for partisans of all stripes. When trying to justify some expansion of power remember this simple lesson that all libertarians know by heart.
When you give government power they will use it as some point in ways that you don't like.
Feminist Biting Beaver is upset that she can't get emergency contraception. Suprise, when you make doctors the gatekeepers for drugs sometimes they will decide you don't need drugs. The government knows better than you - at least that was the justification when the policy was initially put in place.
It would do everyone a whole lot of good to think about how policy can be used for ill and use that as the basis for approval as opposed to the good that it can do. It would save all of us a lot of grief.
