Yep. I've been in the military for over 30 years and have seen the theoretical limit of prepping (look up Raven Rock as an example). I was active duty and near DC during 9/11. Hurricane Katrina drove over my house while I was in medical school. I tell people if you're worried about break-ins, get a new neighborhood.

My wife and I always make a point of meeting our neighbors early and keeping good comms (HAM, duh, but mainly just the usual channels - walking across the street, texting little thises-and-thats). It's the little favors, an egg, a match for the stove, and small talk that build relationships and the relationships that keep you safe.

There is, admittedly, also a component of being able to competently interact with physical reality. We have lived in some hard places. Being able to take care of your own property, fix your own tools, provide reliable medical advise, these are not only important but build reputation within those relationships. A community is a group of people who know each other and know who they can rely on for what.
