I understand your POV just fine, but you’re forgetting the end of the movie. Or, you would be if you had gotten to that part.
Luke astro-projects himself to Salt Lake Planet, gets shot at by gorilla walkers, has a non-lightsaber duel with Darth Millennial, then dies of a broken heart, inspiring broom boys throughout the galaxy to get creative with their sweeping.
I can read synopses with the best of them.
