I'm in my mid 50's and a number of peers from different circles have all come to the same conclusion: they want to create intentional communities of friends to age with. One couple purchased several acres of land and has two friends living in a tiny house with them. Another friend is trying to raise capital to build the type of apartments/dormitories that the majority of US city-dwellers inhabitied in the late 1880's…
Have you tried it? Perhaps rent a big house together for two weeks. I remember roomates and it wasn’t great A pedestrian neighborhood in a city can have a real sense of community. You get to know the shopkeepers, restaurants, neighbors. You might try that for contrast. More durable, less risky, hundreds to choose from. You can even invite your friends to move there
I liked it, I had no complaints except for not enough fridge space (we had two) and not enough craft space. I would need a shed for my ceramics. I could definitely see myself doing this.
EDIT: Oh yeah, I was dating at the time and it was about 50-50 between people who thought it was cool and people who were like "no effing way."
