>Even in this industrial society it is possible to buy raw ingredients and cook yourself and many people do it.
Those raw ingredients are also "industrial products". Did you think that bag of flour you bought was hand-milled by someone after they hand-picked the wheat? It came from a factory, just like most store-bought bread.
Actually one can buy hand milled flour, but I do not think that makes sense. I am not against big machines (and milling has not been done by hand for centuries). I am against adding all kind of things into my food, that happened to not be proofen cancer inducing yet.
I never tried to buy it myself, but I know I saw it on a organic market (in europe) advertised as such at least once. Basically, a extremely esoteric niché obviously.
