I'm a voluntaryist and didn't know it.
How does voluntaryism differ from anarcho-capitalism?
They are basically synonymous although Voluntaryism emphasizes mutually voluntary relationships. "Voluntaryist" also sounds better when introducing it to new people whereas anything with "anarchy" in it will tend to work against you. For a personal philosophy I prefer "Autarchy/Autarchism" because it takes Voluntaryism to the next level of individual development - it focuses on "self-rule" and "self-mastery. See:
http://centerforselfrule.orgIn my opinion, here's the scale of "freedom philosophies" in order of their development:
1. Autarchism (self-rule/self-mastery)
2. Voluntaryism (peaceful relationships)
3. Anarcho-capitalism (which is really just unadulterated Capitalism)
4. Anarchy (without ruler)
