Part of me would really like to join an intentional community, though if it was a "prepping" community of any description, it would get crazy very quickly. If it was simply "move to within a 5 mile radius of Muggleton", that might work better. but as soon as you set up a niche community, it's bound to change. Some people will see it as growth, others won't. For instance, say 10 households established a community, and mine was one of them (its just me, I really have been a lone wolf in some ways, more of that later if it would help). To me, one of the crucial things is that religion shouldn't play any part in the public life of the community. But say 3 households set up a "house church" - they're going to talk about community stuff there, it's bound to happen sooner or later, and I'm automatically excluded from that. Or the next 5 households to join *do* want religion to be part of the public life of the community: pretty soon I'm outvoted, and things shift. And just like that it's become a place for me to avoid - but if it's a gated, intentional community, how do I extricate myself financially? Who will buy my holding? And what approval do they need from the existing community?
"In Muggleton village, or within 5 miles of it", is the best its going to get for me - we'd still be outnumbered by existing/ "normal" inhabitants, but my guess is that in any village there's a fair bit more self-sufficientish sensibility.
In practice, for me, it's not going to happen, even though I'm not very attached to my house or my town where I live now. My health isn't wonderful, and I'd be too old, quite frankly. One of the games I played during my enforced offline time was to imagine a societal breakdown, and how I'd cope - in the scenarios where I do well, I'm 30 - 40 years younger than my present day age. In the scenarios where I'm my actual age, I'm dead in maximum 6 months, after miraculously finding time to bequeath all my prepping kit to my sister, who has adult offspring.
