Earlier quoted context omitted.
It doesn't assume anything. It's literally what's happening right now. All of your neighbors don't want to steal all of your stuff. Think about the fact that this is only true in certain places, regardless of what laws exist. Laws have very little effect on criminal behavior. Your peers being cool people are all that really protects your safety and your property.
Sounds like the solution to crime is therefore to mitigate the factors that precipitate it. If people steal in order to meet their basic needs, then providing basic housing and medical care to all should see a reduction in crime.
I can agree. Now who will do the building and who will pay them to do it?
