I must come from a different planet than EY. The critters that took all the food of the other critters had more baby critters than the no-food critters, and the no-food critter babies were sickly.
Eliezer’s point is that those critters didn’t get the whole pie by arguing that they should get the whole pie. Instead, they just took it. Thus, people are evolved to appeal to fairness to convince others to give them one-nth of the pie (where n is the number of people), but not to give them more than that. Dennis could try saying that he should get the whole pie, but other people are unlikely to agree, so this approach will leave Dennis hungry.
Just taking the whole pie by force is an altogether different approach, which Eliezer wasn’t talking about
