Why Luke has robot hand? In ESB he had synthetic skin. Is it because of budget restrictions?
Real reason: To remind normies that don't remember or don't know that he has a robot hand.
Probable in story reason: A constant reminder to Luke that anyone can turn to the darkside, even himself.
Because otherwise it would be less obvious it was Luke. But they wanted people to see the robot hand and go "I REMEMBER WHEN HIS HAND GOT CUT OFF!!!". I still think it was a good choice though. It looks a lot more interesting than just a regular hand.
It probably felt better to jerk off on that island off ireland with no synthskin or whatever gay shit it is because he couldn't feel his cock with his hand. Like when you sleep on your arm and it goes numb.
I assumed it was damaged in some way and he just never replaced the covering.
I think it was also a good visual shorthand to let people know it was luke in the fladhback, as you can't see his face. (Then again they could have just shown his face but I dunno, I didn't direct the fucking thing.)
This, he also wore the black glove on that hand the rest of the movie due to the damage. I assume Luke never had it fixed and the tissue covering his machine hand just disintegrated or rotted over time without proper maintenance.
