Even if you did steal the facility for growing food without getting your ass shot to pieces, how are you even going to use it? You don't have the knowledge required to operate and maintain the system, nor the knowledge to grow the food, OR the will to obtain it.

Thieves are amazingly dumb and uncreative people. It is sort of like all the South African farms that were forcibly stolen from the white farmer. The thieves still starved because they didn't know what the fuck they were doing even though they had the farms.
