True, centralizing Govt or food, or any of the other things of life is dangerous, it means the few control the many..Corporate farming is something denounced also by Wendell Berry, both in his fiction and non-fiction books.
Wide diffusion of productive property in the hands of people/families is best, keeps the few from having a stranglehold on food, water,etc
Recall teh Omen, part 2, that was what was discusesd-buying up corporate farms to control food production and bring world under heel of Damien......also, the movie Total Recall, where one man controlled all the air on Mars, he used it as a means of control, wealth and punishment....
