I don’t think the federal government should be involved in abortion, contraceptives, marriage or a plethora of other things. There’s absolutely no reason people in Seattle should have any say in what people in Miami are doing in their bedrooms. No reason for the federal government to be involved (if they want to bucket people into different classes like married and unmarried, the federal government can adjust its tax policy, not have the courts create rights).
Though I’m not an expert, I’d imagine the behaviors you list from Texas, like bans on interstate travel, are unconstitutional no matter how you look at it. And if Texas is that restrictive, people can stop flooding there from CA and go to AZ instead. Other options.
