My point is exactly that, that states do have a right to self-regulate, notwithstanding constitutional questions. The end-position that you describe would be terrible, but it's very possible. But I don't think the states would go down without a fight, and I don't think the Supreme Court should ever be looked at as a slam-dunk; many Presidents have learned that lesson. It would be a very awkward argument that the Feds know garden hoses best, at the same time that the Feds are saying that States know health care best. And courts so far have shown themselves willing to consider what this administration has said in recent history about the Muslim/Travel ban to judge intent and constitutionality. So the two self-contradicting points of view ("We know best," "they know best") are likely to get some scrutiny. Just because things look dark doesn't mean it's over. Even if you're a cynic.
