No I would not agree. Neither would farmers or hunter gatherers for the last several hundred years because they would also keep stock piles of food. If they did not they would never make it through a bad winter or a bad harvest.I don't disagree about storing food. I just think being able to provide for one's needs is just as important.
To me.....it's much more important. Which is why food is actually not something I have to worry about much.
Besides, wouldn't you agree that a person that can grow and raise a significant percentage of their food is better prepared than the folks that merely buy and stockpile?
Also time and other resources can produce a LOT of food right now very cheap. Post SHTF producing the same number of calories may cost many times as much. Look at how cheap a 5 pound bag of flour is currently. It costs less than most people make in 1 hour. In a post SHTF world where gasoline and other energy sources are limited , it is unlikely one could produce 50 pounds of flour with one hour of labor.
I am certainly not knocking skills or producing ones own food. It is just that unless you have a profit producing food production business now, food production post SHTF is likely a back up plan not a good first option.
