Always interesting to hear people with resources and not in a disaster tell others without resources and in the middle of a disaster how they should behave. The reality is that while those of us who are reasonably well prepared can get along for a while when faced with a disaster, if you have ever been in such a situation, you quickly discover that personal energy and capability is far shorter than you thought it would be. Exhaustion is real.
Ever actually try to hunt and fish for food for a family of maybe 5 for a period of say 3 days?? Easy to talk about, hard to do on a schedule dictated by hungry tummies. Yep, maybe if you are in a scarcely settled game rich area you could do it for a few days, maybe a week. However, as the American Indian discovered, when people begin to take resources faster than replacement rate....food gets hard/impossible to find. Veggies take a while to grow...and it has to be the right time of the year...and preserving for long term is non trivial.
In a disaster, you run out of stuff quickly...note the long lines of people with a 5 gallon can waiting for gas for generators....etc... And replacing batteries, diapers, water, fuel, tires, parts, whatever breaks, is no longer a simple trip to the store. You just do without or use less effective methods.
Now, throw in the oft cited specter of attacking hoards wanting the remaining resources you do have because they are completely desperate, and suddenly you are no longer performing the tasks of providing food and shelter but now are also tasked with security although the other needs have not diminished.
Yes, I have generators, hundreds of gallons of gas and diesel, multiple vehicles, weapons, all sorts of tools and knowledge of how to use, etc. Nevertheless, living in a community hit by tornadoes which have killed dozens and injured more, I realize that preparations I make can only ameliorate the effects of a disaster for a while...sooner or later, either services and support systems are restored, or things go down hill and not in a good way. I recall the following poem:
No Man Is An Island
No man is an island,
Entire of itself.
Each is a piece of the continent,
A part of the main.
If a clod be washed away by the sea,
Europe is the less.
As well as if a promontory were.
As well as if a manor of thine own
Or of thine friend's were.
Each man's death diminishes me,
For I am involved in mankind.
Therefore, send not to know
For whom the bell tolls,
It tolls for thee.
John Donne
