I really hope they just shutter in the US.

I hope so too. I've heard a few talking heads with a modicum of ability to read the room pull a "umm well actually it's not a ban, they just have to sell it" card since this started to pick up steam. Even goddamn Trump can read the room. If Genocide Joe signs this, it's like the Dems are trying to see how low the youth vote can get.
