The celibate monk thing goes back to the 1974 screenplay but was dropped in the actual movies and the EU. Only to be recanonized contexualized in the prequel. Like midi clorians being too similar to the Kaiburr Crystal as a way to describe the force. its something that should have not been revisited.
My opinion.
The weird thing is, I recall an interview from the early 2000’s where George stated that Jedi actually aren’t technically celibate. They’re just not allowed to have emotional relationships, but it’s technically okay for them to have sex. Which is weirder to me. I need to find where he said that.
The thing is that I feel the PT movies make it clear that this harsh Jedi way with no attachments is directly responsible for Anakin’s fall. That and they are blind to Palpatine and his influence. I think that is the real point of Qui-gon. While he is as aloof as any Jedi in the PT, he is not as harsh as Mace. He’s not as bound by tradition as Yoda. He was a student of Dooku who fell to the dark side. Obi-wan comments that he would be on the council if he just conformed. It is that non-conformity that I think Anakin needed to be successful. He needed the tools to deal with his issues where the main Jedi order was telling him to not have issues. It is like telling a drug adict to quit vs. sharing with them the tools to do it. I think Qui-gon is the only Jedi who had the tools Anakin needed. I thought that even before I heard that this was how George was thinking (Duel of the Fates - so it dates to TPM).
Agreed, and I think Palpatine sensed and foreseen that, so he made sure Darth Maul killed the master Jedi Qui-Gon.
