Well it's the very essence of statistics. You probably can't predict how many of your friends will reproduce and how many offspring they will have, but you could definitely predict the average number of offspring the current population will have. Even though the "model person" with 2.1 children doesn't exist (can't exist even) it's still a thoroughly useful generalisation.
