Robert, I think you pretty much covered the basic principles of money throughout man's timeline. It was very direct and concise while still able to create a mental picture of usage.
One suggestion I would make about the Industrial Age is that I wouldn't say that "money wasn't important" during this era. I'm certain that the generation that experienced the Great Depression of the '30s would disagree with this statement. The main reason why they were so depressed was because they had no money! It WAS important to them for the survival of their families and were willing to risk much to get it, sometimes even their lives. Anyone willing to risk that much for a thing, it must carry some weight of importance.
A better way to state the idea of money in this era might be to say that "money began growing in importance, but was still not a high priority for the security of their futures due to guaranteed salaries and pensions" or something to that nature.
