Voluntaryism: One Creed to Unite Them All

My latest column is now up, it begins:

The voluntary principle, that relations should be voluntary, or not at all, separates voluntaryism from other political philosophies in that it matters not the ethics behind some use of force, but in the setting aside of the use of force in lieu of persuasion and other methods of nonviolent action. In other words, voluntaryism can bring together libertarians, anarchists, mutualists, anarcho-capitalists, and left-libertarians under the same voluntaryist creed. Once united under the voluntary principle, their differences become questions for economics and legal polycentrism. What do I mean by that? Let's see.
