I'm pretty sure I've never claimed there would ever be a stateless utopia. That's the fever dreams I early communists. Human existence is always different grades of hell. But if you want examples of active anarchy. Our conversation here is one. Neither of us is forced to engage. Most interactions in our life are voluntary and anarchic. And this is good, since neither of us are forced to converse, that limits the verbal abuse and incentives using reason. I would believe power should only given to people through voluntary means. IE I trust my surgeon, and so I accept his orders within grounds of his expertise. Any power taken through violence or threat of violence is not moral, no matter the pageantry it's is wrapped up in. I understand my view will not be accepted yet, but I'm willing to meet half way by supporting massive secession of polities.

And as an FYI I'm not a libertarian, I am an anarchist.
