You have been offered the opportunity to show us some high civilizations created without benefit of a city.

Why don't you show us some cities that have been created without the benefit of an agricultural base to feed them?

Actually you should know that the earliest cities had the fields protected by the city wall so there was not the great division between urban and rural which resulted from the cities' growth.

Barring times of famine providing a society with food is not the greatest problem it faces. Without the arsenal and leadership of the city the countryside was regularly looted by invaders. Without the technology and knowledge base of the city the agricultural regions are sinks of poverty and ignorance. Their productivity explodes only when that knowledge is applied to the farm without this it remains subsistence and poor.
