Requiring people to buy a widget is way over the line.

I would say there's a decent chance that part will be struck down.

I just don't see in the Constitution where SCOTUS can't rule certain provisions of a law as unconstitutional and leave the rest.

Is there a precedent in case law, perhaps?

That is what the pundits call a “sever-ability” clause. If you cannot parse it then the entire thing is dropped.
