That's some of the finest advice and way of looking at life I've heard. You've adapted to your surroundings ensuring your survival and safety.
I grew up in a time when the neighbors on both sides of my parents house could just walk right in, as well as we in theirs. We'd have summer water fights that involved an entire block or two. We could always count on each other for that emergency ride to the hospital of if the car broke down, a ride to the supermarket or school event.
My dad used to work at the studios and he'd bring home 16mm versions of movies and TV shows. He'd set up in the driveway with a big pull down screen and spool the film up in the projector. My mom would make the popcorn, hot dogs and set out the chips and sodas along with the seating. When the sun went down, the neighbors would all gather round and we'd watch the shows.
Now it's every man for themselves and who can be the local warlord. They'd laugh at the notion of any kind of social contract unless they are the ones dictating it, regardless of how you feel about it.
Sounds like you'd be a great neighbor.
All the best,
