Do you want me to explain further, or do you see it?
"this lightsaber Luke had fashioned himself in Obi-Wan Kenobi's abandoned hut on the other side of Tatoonine, made with the old Master Jedi's tools and parts, made with love and craft and dire need."
A Jedi does have to create his own lightsaber - this much is true. That being said, did you think he pulled the knowledge out of thin air? Funny that Yoda taught Luke to lift rocks and do flips, but according to you, he learned how to build and wield a sword all by his lonesome. Seems to me that's the harder stuff.

As opposed to the "Let's dump on everything Star Wars, OT and all" mode? You go right on ahead and contrive the worst of everything in these films, for all the good it'll do you (which it won't - better have your blood pressure checked.) It doesn't affect my appreciation of the films at all.
I have far better things to do than watch you troll around and ruin every aspect of the films that you possibly can, though only for yourself.
