Exactly......Mutual Aid/Assistance. Network, Group, Pact, etc. With the wife and I, how long do you think the two of us can …….Pull Security, Prepare food/cook/clean, cut/split/gather firewood, collect/gather water, etc. etc. etc.? Eventually, one or two of us need to SLEEP. The more people you have to carry the "load", the easier it will be. Location also determines "work load". Me at the end of a cul-de-sac? Easier to secure than say a regular square block in the middle of the San Fernando Valley. Avenues of Approach are pretty easy to predict and therefore secure. With basically one avenue of approach, the "security requirement" is simple. The city block in the San Fernando Valley would require 360 degree security.....at ALL times. LOTS of people are required for that.
So, now here's the downside with a MAG/MAN/MAP etc. Typically a MAG requires that everyone IN the MAG has a baseline of certain things (firearms/food/medical/etc.), say 1000 rounds Pri, 250 rounds Sec, 1 years worth of food for each family member, IFAK kit for each family member, etc. The question becomes, how do you insure/verify each family HAS what it's suppose to? Does it become a "Military" environment? Do you have full layouts in the middle of the street? You are RELYING on these people for your LIFE.....trust but verify fits in here.
What are becoming popular are, for lack of a better term, communes (communal living communities). Groups or individuals are buying large acre tracks, and then set up living arrangements (typically simple houses, but can be even trailers/motor homes etc.). Rich people do it with very expensive underground bunkers with every luxury.....not rich people do it with whatever means they can (including doing it "off grid" to lower costs). Typically, whoever is running the MAG/MAP/Community ensures that everyone moving onto the property has the minimum requirements OF the property. Quite a few of these type of communities typically have something at their core in common, such as religion. This gives the community a definitive common belief system to work with/for, and cuts down on the disputes, etc.
What these communities tend to be doing, is "bugging out" BEFORE the "event". They are setting themselves up to live as simply as possible, in anticipation that it will be exactly how people will live AFTER the event anyway. They already HAVE the garden going, the animals (goats/chickens/etc.) in rotation, the water sources (rain catchment/ponds/hand pumped wells/etc.). They typically live a much simpler (in some ways) life, without chasing the "keeping up with the Joneses" mentality of dual incomes, multiple vehicle, McMansions, etc. While each family MAY have a single source of income (to maintain the vehicle, buy construction materials, etc.), the focus is much more on the homestead/home/family. A GOOD example of this is Shofar Mountain (the name of their community) run by Pastor Joe Fox. He's got HUNDREDS of videos on YouTube about what they're doing and how they got there.
"Lightfighter Island" could always be a reality. There's always the ability to buy large tracts of acres all across the country, and moving multiple family groups onto it. The question becomes, who is truly willing to do it? Who is willing to walk away from the "Rat Race" and chasing the all mighty dollar, to live a harder but simpler life? Who is willing to build it up from scratch? With OUT the benefit of multi-millions of $$$? Who is voluntarily willing to become an "Indian" in a community, vs. a "Chief" of their own home? All kidding aside, it would take a special group, with a laser beam focused singular purpose of intent, to be able to make it work. It would require EVERYONE, to place Principals before Personalities.
The other side of the coin is...….What do YOU bring to the table? What SKILL do you bring that would make you VALUABLE to a community? "Gunslinger", unless you're a former "Delta/HRT" shooter, doesn't cut it (exaggeration, but you get the idea). 18D like (PJ/Corpsman/etc.) medic, communications, construction/engineer, gardening/animal husbandry, etc. These are valuable skills that you can bring to earn your place in the community. Of course, there's more, those are just examples. SKILLS are always in need...… another mouth to feed? not so much.
