Yeah, thats true, but since the division of labor has rendered (almost) every worker without the skills to be self sufficient he has no choice but to cooperate with other workers. "If we dont produce food, they will not produce milk or phones or music, and we will all suffer. Lets not." Is that motivation enough for you? The worker has no choice, to fulfill his own needs he needs to fulfill others, he cant choose to shut down production because then everybody chooses that. But yes, there will always be free riders and somewhat of a tragedy of commons, but that exist today also in the present system and i dont hear people using it as a reason to abandon capitalism or market friendly policies.
