Let's say that this ends up in the Supreme Court, and after a whole bunch of back-and-forth the 'mandate' clause is struck down. Now what?

As mentioned above, they forgot to include a severability clause. With such a clause, part of the bill could be struck down and the rest remain intact.

But they didn't include one, which means the whole thing falls.

Unless they simply “deem” it severable anyway.
