Corrosive consciousness is better imo.
Civilization to me is the physical manifestation of the logic of domination, a collection of machines and living things acting in concert to surpress "wild tendencies". All physical things that can be subverted and attacked. So I kinda like to see all leaderless anti-state action, as action against civilization. I'd have to know what you mean by ungovernable though, because to me being ungovernable *IS* being anti-civ, but it sounds like the way you're using it is a bit more loaded desu.
