That you don't see one just means that you don't see one and by shouting down anyone else who disagrees, as the HN hivemind has in every crypto thread I've seen to date, doesn't mean one exists, it just means that in this community a valid and good use case may as well not exist. People, including me, have tried to explain, many times, the valid use cases but HN at large disagrees and has made that distaste clear. That's fine but you'll forgive us for giving up. Those you disagree with aren't idiots, they just have a different perspective and don't see it as useless.
