There's that angle, yeah, but it's the creation of a single point of failure that I was thinking about. And not even in all that tech-centric a way.
My hometown used to make a sizable chunk of the US's fasteners, and there was real concern during the Cold War that dropping a single bomb on it could cripple the entire nation's industrial capacity. Here, it seems like there may be an unacceptable strategic risk that a bomb dropped on Moline, Illinois could cripple the entire nation's food production capacity.
