it all comes down to capital . the way your describing, you already own the land so no cost there. you've already paid for the internet infrastructure. so those historical costs are mute as your not asking to be recouped for those. the costs of building or upgrading the water/ food production storage systems will have to come from somewhere. either each to his own or from a central commune *bank* there are attractive aspects to what you describe and some cooperative communities existed in the 20s, 30s and 40s in Mississippi of all places that were very successfully. eventually the racial and gender hatred of the surrounding communities is what destroyed them in that area.
Calling this endeavor a CULT2.0 is misleading due to the overwhelming negative aspects of cults and religion in general. I rather prefer some sort of social experiment or for that matter a low/no cost off grid homestead co-op.
I think the water infrastructure cost will be the hauling, I can get the containers, filters, test kits, so the fuel for the hauling will be the major hit, about $30/month per resident. If they can kick that much in great, if not I can absorb if needed.
As mentioned earlier, I can afford the goats, vet visits, supplemental feed, additional water hauling for the goats (although for the animals, a half acres of rain catchers will cover a lot of it), etc.
Additional food could be done using communal meals, or if those present have food stamps they can use those (although I recognize some view this as living off the government, I don't personally object to it and my income taxes go to pay for it, so I can accept that some people need that).
Mississipi, I've only driven through. Sad to see they ended that way.
Overwhelming negative aspects get assigned to a lot of things. Ive got family that consider squatters and travelers to be overwhelmingly negative, and they attach all of that as soon as they hear the word and apply the idea they have in their head.
The very few I'm looking for will be the ones who can see the idea, and have it be different than what they've already decided it has to be based on other things.
The progression of this has been very interesting. An idea presented, "oh that's a commune", and when I describe how it may work, "that won't work, that's not a commune!"
One thing I've learned about this is its definitely not a commune, because I'm hearing a huge amount of baggage that comes with that.
I think "people living for free in RV on some land with internet and non-conventional infrastructure without having to pay into a commune" is a good basic premise, but add to it a central meaningful belief that rejects having to pay in and requiring so many things.
There are people trying to survive on very little right now in very bad situations, and if the communes were solving that problem, it would be solved. Maybe there are other ideas. This is just the development of one.
