Because humanity is not about minmaxing a game where output is the most important metric. We are humans, and a human thing to do is sports, we love being impressed by other's physical prowess even if they are narrow and of no economic value. Why do people paint? Or make music? Or play football (whatever version of it)? Because we like to do it.
