I agree that a ruling against the current ‘regulatory state’ is unlikely.
On the other hand, consider the ‘mission statement’ implicit to the EPA; “Protect the Environment”. Does anybody know of any restrictions, other than practical politics, that limit the EPA?
In an explicit world, OR in a modern Twilight Zone, I could see the last EPA employee, having seen the last human corpse properly composted, offing itself in another, automated composter, thus accomplishing the task of “Protect(ing) the Environment (from humans)”!
And they set up “Administrative Law Judges” to determine compliance with said regulation. I never understood how a judical system could exist constitutionally outside of the federal courts but it does. (Military is the exception and is constitutionally allowed as a special case.)
