And honestly, I do think he knew that. It’s just that no one wanted to do the prequels for him, because this was when everyone still thought he was a genius - Spielberg and whoever else didn’t want to “ruin his vision”, or deal with the pressure that would come with doing them.
We can be cynical about it and theorize no one wanted to do it because maybe his initial treatments of the prequels were terrible or whatever, but I don’t think anything about those movies and its ideas ended up seeming un-doable by anyone. You definitely could have made something great out of a lot of thematic stuff there. They still worked to some fraction of an extent, despite of what you think of those films. People then just had faith (a little too much) in him, or just didn’t want to help him.
So I think characterizing him as this narcissistic crazy guy is a little wrong. He’s been very open about his insecurities about this “movie for 12 year olds” he made in 1977. It’s why he continued tampering with it long after they were released in theatres.
I don’t even think his ideas are too far out there, he’s actually responsible for reigning in/veto-ing the more out there ideas that never made it into the prequels and Clone Wars animated series. So we know he has/had a somewhat specific vision (he’s not just doing whatever the hell he feels like) - he just needs to organize them, or get someone to organize them for him, and learn that some things - like the OT - were fine and don’t need to be fixed.
Stuff like “he hates his fans” is just self-victimizing and immature, and is only ever true when you start saying stuff like that to antagonize him. I mean no disrespect to anyone who genuinely believes he was out to get them by not releasing the OOT, but I do hope they get some perspective.
