Tilting at windmills is not just about imaginary enemies. From Wikipedia:

> The phrase is sometimes used to describe either confrontations where adversaries are incorrectly perceived, or courses of action that are based on misinterpreted or misapplied heroic, romantic, or idealistic justifications. It may also connote an importune, unfounded, and vain effort against adversaries real or imagined for a vain goal.

People who incessantly complain about the evils of all governments -- a key clue here is referring to "the state" as a singular platonic entity -- as if they know of some better solution, when they clearly don't, remind me of the above.
