I suppose we could close all food shops other than Asda, and restrict Asda to selling only their most basic range (and no sweets, chocolate, fizzy drinks, etc- after all, you can survive without those). On the other hand, that would mean that Asda would be more crowded as people who normally shop in your "chi-chi local middle class deli" now have to go there.
