Cutting out the middleman (grocery stores) won't remove the hub and spoke architecture. Particularly when it comes to staple commodities like flour, salt, sugar, etc -- grocery stores by and large buy these items from the same small number of distributors. Grocery and food distribution in general have been consolidating aggressively over the last decade or so. More can definitely be done on this front with regional produce or prepared/processed foods though.
