When a governmental entity exceeds its legitimate authority, then it rules by deception and force; by usurping the legal authority from its citizens thru deceit and/or extorting its subjects by threat and intimidation.
"It is unfortunately none too well understood that, just as the State has no money of its own, so it has no power of its own. All the power it has is what society gives it, plus what it confiscates from time to time on one pretext or another; there is no other source from which State power can be drawn. Therefore every assumption of State power, whether by gift or seizure, leaves society with so much less power. There is never, nor can there be, any strengthening of State power without a corresponding and roughly equivalent depletion of social power." Albert J. NockReturn to Government Models.
