[Star Wars] Why do Jedi bother learning how to duel with lightsabers when the only enemy that uses them has been dead for a thousand years?

You try attacking a lightsaber wielding Jedi with a blaster and see what happens.

Other than still being quite effective on the battlefield (I'd say they're even more effective when they don't have other wielders to stop them) lightsaber rituals are a hallowed part of Jedi doctrine. They are a symbol of a Jedi's authority and a personal expression of themselves. They also serve to teach young apprentices focus and discipline and the importance of the physical aspects of being a Jedi and the Force in general.
