It's presumably a huge amount of work. There's the work of setting up the shoot and the performance itself, then the photo editing, managing and interacting with your community constantly, marketing, dealing with the finances/bookwork, researching and buying new equipment and clothing, etc etc etc.

Just like successful twitch and YouTube channels, the behind the scenes work is hugely underestimated.

You are trivializing the work of someone without any apparent understanding of the actual labor involved.
