It’s much harder than you expect. If you can find the right sort of people to join you in a community, then it’ll help, but nothing is as simple as it seems when you’re thinking/dreaming about it. For a start, you always need money. Fact of life. (at least, modern life!) If you have a good chunk of cash to start out, or a private income, then it’s not so hard. I’ve been trying to do this sort of thing all my adult life, with some success, but not a great deal. Everything takes longer than you expect, costs more, and is more difficult. That’s not to say you shouldn’t want it, or try to do it. Just giving you a little warning lol. It’s not an easy life. It can be a good life, if you are not too difficult to please, don’t mind a lot of hard work and can be happy living under very basic conditions. Oh, and you also need to be very resilient, easy going, and diplomatic if you’re doing this with a group of other people, because there will always be disagreements about how you live and do things.
Good luck with it though, it’s a fantastic ideal :)
