To be honest, this is the inevitable downstream result of the dysfunction in US government. If you can't get your policy positions legislated and instead use executive power to regulate through things like the EPA you have to assume those regulations will be reversed by the next executive. It's the same sort of dangerous game the GOP has played by trying to legislate through novel arguments in the Supreme Court - yes you get what you want today, but longer term all you're doing is establishing that the Supreme Court change just dictate policy based on political positions. All of these novel approaches weaken the democratic core of American government.
