except for the water which i could get from a spring,a big one..or a local lake i could walk to in a few minutes i have all those things,plus,and i did not plan it that way i just do..however..this all smacks of 1950's cold war hid in the basement thinking.unless you live in a earthquake or storm zone no one needs a two week supply of anything.fear mongering is a good way to sell stuff and i'm old enough to have see several waves of this sort of thing pass thru several times since the 1950's.
