This is something I have never been able to answer myself, so let’s see if anyone here has an answer for me.
We know from interviews that George Lucas didn’t necessarily think he would get to make sequels after making the first film. That’s why when he went to make ESB, he said he need to make a new mentor figure for Luke to continue his Jedi training.
However, in order for Luke to know where this new mentor was located, Lucas brought back Obi-Wan as a Force Ghost to tell him. So, if Obi-Wan could have continued Luke’s training himself as a Ghost, what was the point in creating Yoda as a character at all? What was Yoda bringing to the table that Ghost Obi-Wan was not?
It was only in the sequels that a force ghost was shown to have any ability to influence the material world through the Force. Without that a living teacher would always be superior because they could demonstrate what they were talking about, for example by lifting an X-wing out of a swamp.
Of course I’m not saying that he should not have been trained at all, I’m just saying that Obi-Wan could have finished the training himself as a Force Ghost. I feel like Lucas could have written it around Obi-Wan showing Luke everything Yoda does in the film. @StephenDutton does make a good point about the X-Wing though.
Force ghosts do not really have the power that living beings do. They cant influance the real world in a meaningful way. So telling a student from beyone the grave 3 years later that the student needed to go find a new master was about all ObiWan could do.
But somehow Im not at all surprised that this child wants to act like Luke should be a gary stew like his rat franchise bitch is.
All Yoda did was sit on Luke’s back or on the ground talking about how to use the Force. How could Obi-Wan not do the exact same thing exactly? That’s not influencing the real world at all. It’s talking, just like Yoda did.
Where is everybody getting the idea that I don’t want Luke to be trained at all from?
