Ludwig von Mises Quote

State and government are the social apparatus of violent coercion and repression. Such an apparatus, the police power, is indispensable in order to prevent anti-social individuals and bands from destroying social co-operation. Violent prevention and suppression of anti-social activities benefit the whole of society and each of its members. But violence and oppression are none the less evils and corrupt those in charge of their application. It is necessary to restrict the power of those in office lest they become absolute despots. Society cannot exist without an apparatus of violent coercion. But neither can it exist if the office holders are irresponsible tyrants free to inflict harm upon those they dislike.
