I think people are aware that the government can physically do a lot of stuff, e.g. shoot you in the face for no reason. And vice-versa for that matter.

And all of those arguments are entirely academic, and subject to change depending on economic status, skin color, or nationality.
Law is effectively a weak gentleman’s agreement we tolerate because the alternative is violence.
(Well, law is enforced with violence too, I suppose.)
