We probably need to do this on another thread, but it seems to me he is making a significant category error. Sport is something "we don't have to do" and in particular watching sport is not something we have to do but the world has a consensus that sport is not art. Few or us need to fish for food, indeed most fishermen throw the food back and yet fishing is not art.
I also think when people ask questions around "what is art" they are generally talking about the a specific category of art, i.e. modernist/contemporary art in galleries. Most people agree that music is art, that paintings by Constable and Turner are art. And similarly most people agree that a repetitive pattern on a dinner plate is a craft skill but is not art.
Art in the conventional definition deals with the "human condition" i.e. emotions and feelings. You cannot know what it feels like to be me and I cannot know what it feels like to be you, we can create representations of how we feel about aspects of the human condition as art, music, paintings, photographs, poetry, literature. As Greyson Perry put it "art is created by artists for the purposes of art"
