Yup, that could also be said about music, cinema and any other form of art/entertainment/distraction. It doesn’t produce anything “useful”, but again, what is “useful” varies from one person to another. Some would say the waste of money is the point. You blow fireworks because you can.
Ultimately nothing matters because there is no true meaning of life, so anything that pulls you away from the dark nothingness of existence is good to take.
