The principle is simple and straight forward; it is wrong to initiate force against another person or group of people. This is by no means a passive or pacifist doctrine; it is absolutely permissible to use force in response to force, in order to protect or defend one’s person or property, to enforce a contract, or punish someone for failure to adhere to the terms of a contract.
Government is a group of people who claim a monopoly on the initiation of the use of violence in order to suppress the freedom of the individual. Anarchy is the absence of government and the absolute freedom of the individual. Anarchy by definition does not mean that there are no rules or organization. It simply means without a ruler. Anarchists want to live their lives without being ordered around by people with guns.
Other people are not your property. In other words: They are not yours to boss around. Their lives are not yours to micromanage. The fruits of their labor are not yours to dispose of. It doesn’t matter how wise or marvelous or useful it would be for other people to do whatever it is you’d like them to do. It is none of your business whether they wear their seat-belts, worship the right god, have sex with the wrong people, or engage in market transactions that irritate you. Their choices are not yours to direct. They are human beings like yourself, your equals. You possess no legitimate authority over them. As long as they do not themselves step over the line and start treating other people as their property, you have no moral basis for initiating violence against them ‘ nor for authorizing anyone else to do so on your behalf.
I believe in NAP (Non-Aggression Principle) The non-aggression principle is the idea that no matter how disgusting, immoral, or improper you believe an act to be, you have no right to use force to stop someone from committing that act, unless that act itself involves the initiation of force against another person (or person’s property).
