I see you are looking at a glass half empty. The single biggest thing that was missing from your comments was (IMHO): LEADERSHIP. Without strong, positive leadership, the group will eventually splinter into different factions with infighting, in various degrees of seriousness.
I also believe that bugging out is a very last resort and would be undertaken when the home or neighborhood 20 is no longer a tenable position. "Untenable position" to me means that there is no water source beyond an inadequate rainfall, no food with no space to grow food and/or sources to obtain food through/from, and/or a security threat in which one will be facing overwhelming force unless a retreat can be made to a more defensible and sustainable location. I have planned on these events in case they occurred, AND NONE of my plans are fool proof!!!
The first casualty of all wars is the pre-wartime planning!!!
Meanwhile I pray, hope for the best, and plan for the worst as best as I can. My preparations give me confidence that we can handle most problems here at home and that gives me good sleeping periods when I am at home in my own bed. What more of life can I ask of it?
