It just means that the entire system has not been captured by insane people that there is still some pushback.
Anyone who believes in the Unitary Executive Theory likely believes that the President wears imperial robes. The idea that the President should have unchecked power over the executive branch is insane and mocks the whole idea of coequal branches of government or checks and balances.
You can argue for reform, but nothing currently going on is reform. It is entirely running on fumes. The recent AI executive order is representative of this as is the constantly shifting policy driven by whoever has Trump’s favor at any point in time. There's nothing grounding any recent policy change of the United States.
I agree with you mostly, but that's beside my point. Some of the things the administration is doing fall under existing executive powers granted by congress, either directly or in enough gray area that it would require court challenges. Removing laws granting those powers should lead to either the administration avoiding the attempt if they know they'll lose in court or courts having a very simple case to deem said actions illegal.
