Here we are talking about the richest of the richest people. I'm sure it is not impossible for the CEO of bitcoins to reach the list , but then the list includes people who have worked their ass off , day and night to build up an empire. Bitcoin needs to be established as an empire first. Then we might get to this point.
All those miners sitting in their room, mining day and night hoping they will be millionaires someday lol. Yes, bitcoin must grow as a community first to be able to reach to a position where people are so rich, they are competing in the world's richest list

Either I am a pessimist or a realist but I don't think so this will ever happen lol. You can't be the richest man in the world by buying all the god damn btc lol. You need money to buy that too
