You can get wifi pretty cheap. A $40 router will get you wifi. You'll also need an internet connection, however......

Yes, of course. Look at Amish communities. Largely self-sufficient and thriving.

People who haven’t tried it greatly underestimate the amount of work though. I’d recommend dipping your toe in with some gardening at home first. Jumping in the deep end will usually lead to failure and disillusionment.

They exist in the world. They are not very popular, judging by the fact that you've not heard of them.

You need much more than 1 acre per person. First Google result is 5-6 per person.

You will need a lot more money, there is more to daily expenses than food and wifi. Also 1 acre is not enough for a sizeable group.

You absolutely can though. I know the preppers forum had one. You see it a lot more in Latin America these days, mostly retired expats and hippies (not trying to be derogatory). I find it's kind of hard to ask people to put in all that effort though when they don't get proper land rights. A commune doesnt offer a stable retirement other than trust me. I always imagine tension can run a lot higher than they should in these types of communities.

Need more than WiFi and vegetables

I'm thinking you don't understand how many acres it takes to feed a few people. I'd be scared shitless trying to feed my skinny family of 4 on a single acre, and that's assuming a constant water supply.

OK, looked around a bit, yeah, we'd starve on 1 acre.

Try looking for crops to grow that are nutritious but relatively low maintenance. Sweet potatoes, sunchokes, groundcover strawberries, asparagus, cherry tomatoes, etc. Bonus if you can grow excess to sell at local farmers markets for some extra income, though the easiest the grow ones probably won't fetch a great price and on one acre I doubt you'll have extra of anything. Also, look for native options. Less maintenance, and local pollinators are more likely to help out.

If you're not squeamish and can get enough extra space with an enclosure, rabbits breed very quickly and just eat grass. Chickens are good for eggs and meat.

Usually in the US they call it a co-op instead of a commune, but yeah, things like that are already done.

All it takes is people getting together and organizing to do a thing. Co-ops exist all over the place. Also plenty of cults have communes. Those kinds suck tho.

In Australia they’re now called ‘intentional communities’. That might help with searching. Some are religious but some are not. Quite a few are just science/sustainability based.

There are a few in my country and theyre filled with the craziest hippies

Community gardens and Internet cooperative are the operating phrases you’re searching for

Depends on how many people you're envisioning in your commune, but you'll likely need more than a one-acre garden. And working that garden is quite a bit of work!

Do you have access to the ground water?

If you really want help, you almost need to dox yourself by giving pretty specific location info. So please don’t do that.

Land matters are very complex in any country. In the USA, laws around land use can vary from one block to another. 50 states and many matters are delegated from each state to their counties for implementation.

My point is, yes, you may be able to arrange such a community.

It can be a tricky legal, political and social affair that is very specific to your exact site.

So plan on a huge learning curve and learning how to find the right kind of legal and organizational advice.

Yeah

What?

With an llc and enough contracts, sure. Have "investors" pay into some cooperative to buy land/startup, then everyone is somehow working for that co-op which pays for everything?

A friend joined a group of people to build a co-op in a house about ten years ago. Shouldn't be any different today.

Google intentional communities.

The wifi rollout thing is tricky... Especially because who do you entrust the administration to? Technically whoever is managing it can see everything everyone in the subdivision does online, and since it's all shared, could be doing packet sniffing to de-obfuscate your traffic and if they're untrustworthy, potentially be stealing your PII. They're already going to have a lot of your PII simply from knowing who you are and where you live, but basically having your entire internet history at their fingertips no less.

It's part of why I refuse to move in somewhere that someone else controls the connection, literally for that reason. I want my own private connection because I don't trust other people with this.

The problem isn’t that it’s impossible, but that humans are so awful they simply can’t do something like this without infighting and bickering and blame.
