No, my idea of capitalism's development is much earlier than colonies and cities. It has to do with you having chickens and your neighbor having pigs. You want pork, and have eggs. So, you trade eggs for part of a newly butchered pig. That works out great until you realize that chickens don't lay eggs in the winter and pigs only breed at certain times of the year. So, to solve that problem, you come up with a non-perishable intermediary that stores the value of both eggs and pork. Something like coins. From there, the world's your oyster.
