I agreed with him when he was simply talking about the cost of violence vs the cost of production, which I don't think you ever mentioned.
Here's what I am saying:
Limited Supply:
The resources we have are finite, and in many situations, the production and/or harvesting rates of the resources are, too. For example, lumber. Here in Minnesota, there is plenty of wood, but the rate at which we can harvest it without significantly damaging the environment is limited.
Unlimited Demand:
The demand for said resources is, over time, unlimited. This isn't just limited to things people want, but also human needs such as food and water. Even if a single person's demand over the course of their life is finite, a growing human population's demand over all time, is not limited. In mathematical terms:
Cost of Production
As resource supplies get depleted, it generally become more difficult and more expensive to harvest them. Think of it like drinking a soda: it's a lot easier to get the few first sips than to get the very last few drops. You'll probably throw the cup away with a few drops still sticking to it. This
would not occur in a world having unlimited supply and unlimited production of resources.
Rational Decisions
This is why the supplies don't have to reach zero in order for a conflict to arise. The cost of producing/harvesting more of your resources simply has to eclipse the cost of a conflict which is expected to produce an equal amount of resources. This is what another poster had said about farmers and samurais. Colonization is an extremely common example of such a conflict - Britain didn't colonize South Africa because they had just lost their very very last diamond. Rather, the cost of the conflict was less than the cost of acquiring more diamonds without conflict. They could have just bought some more from other countries, right?
Resources, resources, resources
Many, many things are resources: manpower, land, air, fresh water, knowledge, food, etc.
Summary
Say you are sitting at McDonald's with a friend, both drinking soda. You guys absolutely love soda and don't value your friendship much at all. You are perfectly happy drinking your own, but when you get down to the last few drops (limited supply), it's tough to get it out. So because you value soda higher than your friendship, you steal your friend's (conflict). Even though you may be satisfied for now, someday your son might make a play on his son's soda (unlimited demand).
Do I think this explains every conflict? Of course not. But I do think it explains
a lot of them. By the way, what I said is the economic concept of http://en.wikipedia.org/wiki/Scarcity" .
