Wars are fought for profit lol I’ll take sports over that any day. 

What has meaning to one person may be worthless to another. Humans create meaning which makes it subjective. Dedicating your life to sports is meaningful to the individual. Just like dedicating your life to music or art. Just because you don’t like it, doesn’t mean it has no meaning. Clearly it has plenty of meaning to millions of people around the world. If people are willing to pay for it, then it has some meaning. 

And how is it dystopian?
