pricey homes in neighborhoods where no one ever talks to their neighbors, and houses are isolated by distance, foliage, and fences.
I've lived all over, in all sorts of dwellings and properties. At the moment, I'm in the sort of neighborhood you have in mind.
FYI: On large properties — when you have private roads, culverts, shared fences lines, trees and other growth, property line issues, etc. — you do have to interact with neighbors. Repairs, maintenance and other issues come up, and this has to be coordinated with neighbors. Properties are often unoccupied, and neighbors rely on each other to deal with things. In the pricier neighborhoods, there are HOA officers that are in regular contact with property owners. In rural properties, where no HOA is involved, you and your neighbors are on the hook for everything, and everything has to be worked out among you.
When I've lived on smaller properties in dense neighborhoods, this is where I've had little to no contact with neighbors. Similarly when living in apartment complexes.
So I think our tech bro coastal city dwellers have a naive view of what goes on on all those pricey surburb and exburb properties they hate so much. It isn't what you imagine.
