I’d argue that I don’t mind the overall concept of the Jedi. They are uniquely separate from any typical soldier. The trials and tribulations involved would make most people pause and wonder why anyone would carry such title. It heightens an image in the public’s mind of how kooky and insane these Force sensitive people are. Admired by some even. But more importantly, an easy target for a tyrannical reigme to throw under the bus.
However, I do agree to some degree that the no relationship mantra is a bit absurd. The Prequel Trilogy would had done right to make it clear that instead, no romantic relationships until you’re well into your Jedi career. Still kooky, but just enough kookiness.
