The issue legally is that health care has always been a state issue. It was never a national issue. If people wanted to make abortion legal, then the state legislature would be the place to do it. We have all kinds of laws, family law especially, where the law varies state to state, even when defining what is necessary to constitute a marriage.
The problem with Roe is that the proponents used inference based on inference in the constitution to create a national right to abortion which was never the purpose of the constitution. The constitution is designed to provide a framework upon which the legislature could build. It has been used by activist judges to essentially rule into being legislative action which would never pass in the normal legislature. This is because the court is picked by sitting presidents with specific goals and then those nine judges sit for life. They are not a legislative body and should not be making law.
If the state legislature of any state passed laws through the normal process defining life as existing only outside the womb, I would still think it immoral and somewhat crazy given what medical science tells us, but I would not have a problem with the legal mechanism. Sorry for the long post.
