Well, there's the problem: large-scale and social are incompatible. Humans evolved to be sociable with maybe a few hundred people.

The scale is the whole system, so many different groups of people.

To take your restaurant comparison that'd be like saying McDonalds is an average sized restaurant, which might be true for each individual McDonalds, but not for the entire system of the McDonalds chain of restaurants.
