This is a typical American political tactic.

You float a bill such as this that is pretty extreme and controversial.

It rallies your political base and gives you brownie points for your reelection campaign as it makes it seem you are doing something. So your base likes it.

It gives your opposition a lot of good ammunition so they can rally their base against you, so they like it.

Ultimately the bill has little to no chance of being passed. And will fail on a constitutional challenge in the case that it does pass. So ultimately it's just a huge waste of taxpayer resources and congressional time to argue and implement or not and it ultimately will have no effect on anything. Which is great because when it ultimately does fail, one side can claim they are actually trying to do shit while actually doing nothing and they can blame their opponents to save face claiming that if only their base was more engaged it wouldn't have failed. Their opponents can check it as a win but "we almost lost" so next time they can use that to further rally their base, even though it's a constitutionally dead bill and doomed to fail anyway.

It's a political game, both sides benefit from it. The only purpose of these bills is to provide opportunities for grandstanding to encourage more fundraising. Both parties do this shit all the time.
