The problem is that normalized sports that are already at a huge scale not only have the infrastructure, but they also have guaranteed income from things like normalized midroll ads from dedicated television networks, some sort of paid subscription to watch, merchandising, and a form of alternative media (ironically video games). Not to mention the ease of access to learning, the fact that it's something kids can do in school, pro teams having rosters of more than 2-5 players, and having multiple generations of fans being in the same family. Esports is no way near becoming as big and it has way too many problems itself.
