The legal system is certainly a flawed creation of man, but it isn't a magic wand. I'd go so far as to say that most legal systems, extant and otherwise, won't (absent corruption) serve as a vehicle for you to do literally whatever you want. I'm not a lawyer, but I get a strong impression that the Trump campaign's attempts to have the election results invalidated or reversed in various jurisdictions were in that vein, and literally laughable.

I agree that revolutions are real, that many have happened in the past, and presumably more will in the future.
