I doubt scarcity has had anything to do with wars for the last 100 years, maybe even longer. It has always been about ideologies, fanaticism, and lording it over one another. Even when men lived in smaller tribes during periods of abundance, they still went around killing each other for false glory, ideology, and expansion. No economic solution can solve the problem of war and human nature.

Even if men ever colonize Mars and the wider galaxy, and resources were abundant, I doubt it would take long for wars to break out there, whether for a specific reason or none at all.
