On the whole, the free state project fails because of one thing, I think: this strange demand that you sign up. I would never do it just because the whole idea of joining a 'group' to support 'freedom' is at its core an incorrect notion. I am an independent, free thinking individual; I do not subscribe to the joining of any, ANY, group in the name of freedom. I subscribe to direct action on your ideals. Joining a group to simply label yourself such a thing is sort of sophomoric and of the old 'red team--blue team' mind set.
I am a liberty activist; I am not moving to NH because my partner does not want to even consider it. It's an automatic kind of thing, that strong of a rejection of an idea within a committed relationship. You can't disregard it.
I most certainly would entertain the notion of moving to NH if I could. But if I did, I would never, EVER, join the FSP.
