I think that while this is definitely true of opportunistic politicians who will take any advantage they can, I don't this is actually true of most people who actually believe in states' rights as a real principle (as opposed to a politically malleable one).

For instance, I have close family members who are strong free-market conservatives (to a pragmatic extent, not anarcho-capitalists or anything) who I consider to be good, decent, and intelligent people.

Across the board they support states' rights to make decisions about loads of things, even those things they personally don't want (e.g. drug legalization, public healthcare, climate change regulation).

Not saying that those tribally-minded "our team must win at all costs" folks don't exist, but those who actually believe in free-market conservative values for their own sake (as opposed to for the benefit of their "team") are, in my experience, just as reasonable as most other groups, and I think we can criticize hypocrisy without painting with such a wide brush.
