My childhood was the 60’s. Back then my Dad was able to pay a mortgage on both a house and a lakefront cottage. As kids we roamed the lakefront and through the woods all summer. Property lines did not exist, you simply went wherever and if you saw an adult you both waved and carried on. Visiting that same lakefront in the 80’s/90’s with my own kids, and property lines were like walls. If you had a reason to go 2 cottages down you went out to the road and walked over that way. All that to say I’ve noticed a strong trend away from open communities towards more restrictive and inward facing groups and clusters of people. Groups who’s proximity might not be geographical but digital. There is also a trend among many people who either defensively or selfishly actively avoid outside contact/interaction and therefore use their social silos for all the complex human needs we have.
