Sure, anything at industrial scale is going to me more efficient than a mom and pop operation. But with a system like this you've got scale and proximity. Instead of having a network of trucks delivering lettuce from California thousands of miles cross country, you can have a small fleet of trucks delivering lettuce within a 2 hour radius. Less spoilage, far less gas, and far less planning and logistics.

This could be huge in cities with abandoned/run down industrial districts that have been hard hit by globalization.
