Government is the tool that people use to form a well-ordered society. Without government to "enforce societal mores and standards" there would be no fire fighters. There would be no roads or highways. There would be no currency. There would be no doctors, hospitals or pharmacies. There would be no citizenship, borders or passports. There would be no "rights" either since the means to protect those rights requires a functioning legal system which is based entirely upon "societal mores and standards". You stated that Libertarians "reject the notion that government should run society" which means that you are advocating anarchy instead.
