And the court didn't rule that Congress can't do that, the court ruled that Congress didn't do that. Congress can absolutely go write a law giving the EPA that authority, and they should. But if that's not what the law says, then that's not what the EPA can do.

We can't be opposed to police creatively interpreting laws to target minorities and be okay with the EPA creatively interpreting laws to target fossil fuel companies. Just because the latter is in the service of a good cause doesn't make it legal. The ends do not justify the means--down that way lies peril.
