Large aggregation is also to a certain degree a moat. Most creators have quickly found that people won't pay for one creator's content unless that creator is a huge volume creator (at the scale of maybe Disney). No one subscribes to a platform with 20 movies and 5 TV shows.
Dropout.tv is a counterexample. They're not 20 movies and 5 TV shows, but they're closer to that than they are Disney. There are also all the people who make a living on Patreon.
