hello - yes that is why neighborhoods must band together - this is essential but I assume that some will make sure to watch their areas at some point - there is no other way - cooperation is stronger than individualism and many people will quickly see that helping each other is better than stealing as it will be all for free
in the long run, the fear of stealing does not make much sense - the way I see it
Agree. Real communities of people you actually know are so important. There is a survivor of the hyperinflation in Venezuela who writes of how he lived in a suburban subdivision. He didn't really know his neighbors and then many moved away so the community became a target for crime with vacant properties and no communal response. They grew their food indoors and left their house looking like it wasn't maintained to blend in:
