Except it’s not even that indirect. The government of Texas invented this novel class of private liability, and their courts are the ones enforcing it. That’s the same as banning it themselves, and blatantly unconstitutional.
I’m a bit surprised they didn’t implement this as a tax. That would be just as bad, but the federal government has a long history of imposing punitive taxes on things they aren’t allowed to ban; it would have been harder to fight it that way without forcing an overhaul of the entire tax system… and politicians are so very fond of special-purpose taxes and credits.
