I think this is interesting and thought provoking as a framing, but I do think it could be greatly simplified. People will either fight over resources, or they will work on creating more resources more efficiently. They will tend to the former when resources are adequate and the latter when resources are scarce. Resources can mean mates, food, land, etc. Growth can be just as impeded by fighting over a constrained food supply as by fighting over reproductive partners. But, it is provocative as stated!
