What is common to all these scenarios is a very deep pessimism about the social fabric - we will be faced with a problem (CME, earthquake, inflation) and society will totally collapse into anarchy and chaos. ....... We will need help. I think it is realistic that we will get it.....Any prudent person should realize that the help won't come right away, and one needs to be self-sustaining for a good bit more than the traditional 72 hours.
In my opinion this sums it up. Preparing in a 'normal' world for TEOTWAWKI is pointless. The 'rules' will change in unknowable ways. If you are a resource rich target, you will be overwhelmed by masses of people wanting what you have. People have been trying to prevent this for centuries, and have ultimately all been unsuccessful.
