I tend to agree with you Rik, I think that it's possible for multiple people to share land, resources etc and be a part of the experience but I doubt that it's possible to have the complete experience. When it comes to multiple people contributing to land, or an island etc then they would basically have to give the money to some sort of trust that's got rules and abide by those rules for ever more.
If we ever collected money for woodland or some such it would be governed by rules we'd all have to abide by so everyone would have to go into it very aware, I do dream sometimes though of having small woodlands all over the UK so that our members can use them as a place to escape to, practice skills etc, they'd still need to be managed and all that but it would be brilliant for everyone to have somewhere they can go.
