It really isn’t possible to abolish the Supreme Court without undoing the constitution entirely. You do that, and you aren’t fixing things, you’re starting over. And yeah, in theory you could amend the constitution to do it, but trying to make that happen is the same as undoing it in reality.

I’m not saying that’s an invalid choice (viva la revolution!), I’m just saying that it is a different concept entirely.

But yeah, if you just changed the first one on that list (which could be done without drastic measures), it would fix 90% of the rest.
