About that: it would have a lot of space and a lot of freedoms about what to do in that space and how to change that space.
I see population density and lack of ownership as two of the big issues that reduce quality of life in Europe. When you live in a rented place in a city, (1) it is almost always a small space with low to zero outdoor space and (2) it is not your own space, so you’re not allowed to change anything without asking your profit-minded landlord. I hate everything about that. The city is just not the place for physical freedom, but the good thing about digital nomads is that they can work from anywhere if they have Internet. And “enough Internet” is not a major challenge – even in backcountry Morocco we had enough, as you know – a bit more expensive, but fully enough.
So what I imagine as my dream space is a large compound (6000 m² or more) in a rural area, with no neighbors around. Our place in Morocco was quite nice … if it would be ours, and if it would be about four times the outdoor area size. With enough space, everyone can do what they want without interfering with each other … it needs much fewer rules. For example, many small businesses can do their thing in such a space. As another example, it would be heaven for people living in a vehicle (like me) if there would be multiple such spaces to travel between, with parking space and modern comforts and infrastructure at each of them.
My best examples for this kind of co-living would be Calafou and also Valldaura Labs. It’s certainly not the mainstream of co-living, though. So take this dream with a bit of caution
In my case, probably bringing tech expertise in such a way that people from the local community can learn some of that over time. For example if I’d stay for a longer time of at least 3 months near @Yosser’s future hackerspace, I would run a weekly 3D fabrication event to explore the potential of the 3D printer together with whoever is interested from among the local community.
