It means that there is NO authority. If there’s no authority, the only thing that determines whether or not a group or individual can wield force (rightly or wrongly) without consequence (which there must be for wielding it wrongly) is whether or not they have the might instead of whether or not they have the right.

If you stop your blind and knee jerk defense of it and think about what I’m saying you’ll come to see that it’s true.
