What is gained and what is lost?
The woman's right to control her own body, obviously. This right would be lost in many states if Roe v. Wade is overturned. It would be a disaster.
I think you are taking a worst case view of this (which is possible, but I think doubtful), I doubt that we would see draconian legislation put forth
Of course we would! Hell, many states already have laws banning abortion as soon as Roe v. Wade is overturned. I think your underestimate the impact it would have. Put yourself in a woman's shoes, do you really want the government controlling your reproductive decisions? Quite a horrifying thought.
and if we did, those doing so would pay a large price.
Quite possibly, but it's still not worth the damage to womens rights.
