Is that a “pat” answer, or is a question?

A little of both.

Agriculure alone did not cause the huge changes we have seen over the last 10,000 years. But when combined with surpluses, leading to walled cities (to protect the surpluses from raiders), craft specialization, accounting (writing), organized armies (to protect the surpluses), and other developments you begin to see the large-scale changes previous posts were mentioning.

Ok. Reasonable enough...
