alt Hacker NewsThat police and justice courts don't catch every thief is not an argument to abolish the judiciary or make stealing legal. That police and judges habitually act in favor of certain people is likewise not an indication that a society without regulatory institutions is better off than one with admittedly flawed ones.
Police and courts have legitimacy because they are created by the sovereign nation. There is no sovereign entity above the nation - you're comparing apples and hammers.
