A static website that shows/hides content depending on your subscription level dynamically?
Patreon gets to take the money they take because they've found a good niche, not because their website can do something that all websites have been able to do since the 1990s.
I personally think they take too much for what they provide. That's all. I am very happy they exist, though, because otherwise everyone would just be chasing the algorithm.
That is describing most money-making websites in existence
