I believe it is the natural right of every man woman and child to live free from initiatory violence and fraud, and that the only proper exercise of violence in human society is the defense therefrom. To speak of these values initially sounds quite reasonable to many. Until they realize it would forbid things like taxation, which nearly all of human society has accepted as necessary and proper for the continuation of civilization.
Even amongst those who have accepted this theory as their mantra, there exists great hesitation to carry it through to its ultimate logical conclusion. That being, if one has the right to use violence to defend themselves against initiatory force, and the government exists solely to initiate force against the populace, and refuses to stop its predations when we ask politely. Then the reasonable man is compelled to do something most see as quite unreasonable.
