I'm not convinced you know what you're trying to ask. What do you mean by "use case" other than the reasons for which people want something? The person you're responding to said that people want it so they can speculate and gamble with it. You can dislike these vices all you want but you're seeming to speak to some objectivity which you haven't done much to explain.
