I am going to be rather more contrary to that, and obviously controversial.
As it is a group set up to prepare for, deal with, and prosper after disasters from minor to major, I prefer a much stricter formal organizations. It will not appeal to very many, and that is just fine. Most will see the initial words and dismiss it out of hand. But if read fully and understood, it will be obvious that not only could it work, it has worked in the past in many places very well, for long periods of time. It does take into account what many will feel to be its biggest weaknesses, though many will not see it that way. And it is just my opinion.
My thoughts on a MAG or group organization:
It would amount to a benevolent monarchy, with whomever becomes the natural leader of the group having the last word in all things. But there would be guidelines such as Rules of Organization based on the US constitution, with a Bill of Rights based on the Ten Commandments, the US Bill of Rights, and the Golden Rule, tailored to a monarchy.
The leader would have two small groups of advisors, those he/she selects, plus a group elected by the other members of the group.
The leader can be changed by a seven-eighths majority decision by opinion vote, or seven-eighths advisor group vote. Open elections would be held to decide the new leader.
All adult members capable of doing so would be required to participate in the various activities required to keep the group safe and sustainable. Those doing so will gain the right to vote in elections and other situations that require a vote, as well as participate in the opinion polls the leader and his/her advisors will conduct to help them make decisions for the group.
Individuals, couples, and families would have to meet requirements set up by the group before being accepted into to the community.
Any conflicts would be resolved through the processes set up in the Rules of Organization, which in my case would be arbitration with an arbitrator selected by the leader or the group, if the leader so choses. Then a regular judicial process. The leader would have final say on all actions.
Just my opinion.
