I agree that the original ruling was ideological, but in the real world the enemy of good is perfect. How many people will suffer in the meantime because of this? How many women in red states will undergo back alley procedures to terminate their pregnancy? Truth be told I really don't care about the intellectual consistency of upholding or overturning Roe, I care about the real world impact it will have on people. It's not abstract, these are real people's lives.
Also that's before even getting into the structure of our federal system and explaining how "states rights" have almost always been a tool for upholding regressive legislature that is unpopular at the national level, due to the fact that a filibuster-proof supermajority is required to reign in the states, meanwhile a dissenting minority within the states has no similar recourse. Why do you think most of the progress in civil rights post-1964 has been accomplished through the Supreme Court? It's because southern and rural states are impossible to reign in with congress. This is why the Federalist Society went through the Supreme Court, because it's technically legal and technically how our government is supposed to work. But the end result is them harming people just like you and me.
