Entirely relevent, and a part of reality in much of the world already, unfortunate and sad to say. Some people will stop acting civil in times of desperation and a lack of authoritative control is presents itself. Our time for such behavior on a large scale will come soon enough. For now, we can continue to enjoy living a soft, relatively low-risk lifestyle.

Equipped to Survive includes planning for the inevitable. If you go out in public, you should expect that sooner or later you will be confronted with the ugly reality that there are a lot of people out there willing to use whatever force they can to separate you from your belongings. No one else is going to stop them. So if you don't plan to, then expect to have nothing eventually. That may be a fine and acceptable outcome for some, but I have responsibilities and commitments still that preclude me from such a carefree attitude.
