If I wanted to leave the US, I think I would be reading this person's stuff first. Seems like he really knows what he's doing and is really happy.
That being said, I think that achieving freedom is a long-term issue and it's going to happen over the course of many years. It's going to require that people be open about their rejection of statism. I'm not going to say that leaving to another country doesn't in some way make the world a better place (I honestly don't know), but it seems to me, that long-term, getting people together, concentrated, who can provide moral support to one another (like the FSP) who are open about their point-of-view is better for achieving freedom.
