What is "nope" about? I understand "people in Government are subject to the same laws as any other citizen" to mean the same as "written laws that apply to everyone equally". The sort of thing Aristotle and Locke advocated for.

As for the separation of powers, it is a related concept, but still a distinct one; not sure if bringing it up helps here.

Added "The Road to Serfdom" into my book queue, thanks for the suggestion.
