Yes. Pretty sure Luke went to the Dagobah system to get training from Yoda and really only tells R2 because he needs him to set directions to the Dagobah system. As a matter of fact, I would expect a depressed Luke to be more likely to contact Leia to tell her he isn’t coming back because she is expecting Luke to be back, hence the search. I mean that’s just basic etiquette. If Luke really didn’t want to be found and stay away, why create a map in the first place?
The novel said Han believed Luke went looking for the first Jedi temple which the map identifies, something also theorized by another resistance fighter. And if Han thought it, he likely heard Luke talking about looking for the first jedi temple and so believes that is where he went off to, just that he doesn’t know where the temple is. So your argument that it can’t possibly be because Luke went for learning/finding something can be possible because the official novelization on brought it up as a potential reason. The reason why Rey, Leia, Han are looking for Luke is because they want to warn him that the First Order is looking for him. I don’t consider the novel canon but it was Disney approved with there being hype that we might see the first Jedi temple.
The name of the planet where Luke Skywalker was hanging out in Star Wars: The Force Awakens has finally been revealed. Get the details here and let's figure out what this means.

Though his presence loomed large over Star Wars: The Force Awakens, Luke Skywalker wasn't around much. That will change in Episode VIII, and here's what we think he'll be up to.

It’s pretty obvious that you are so fixated on the idea that Rian Johnson’s idea was flawlessly perfect and no idea could possibly work that you also go against the official novel for Force Awakens. No one is discounting the possibility that Luke was depressed although the article above hypothesizes it is because of Ben’s betrayal+Ben and Knights of Ren dest
And fear of the possibility of Kylo Ren dismembering him means Luke is afraid of Kylo Ren. Unless getting dismembered is not scary? I mean it seems even you agree that Luke is scared of Kylo Ren but somehow want to argue running away from confronting Kylo who wants to fight him is not cowardly? I think Poland wants a word with you.
Ofcourse, being so scared of Kylo because he is so powerful could be a good reason for Luke’s depression and hiding/cowardice. He sees an enemy so insanely more powerful than him that he cannot hope to best who will destroy everything his loves would be amazing characterization to build up Kylo as a threat.
But if that were the case, Kylo is a paper tiger. Looks scary but accomplished nothing. Loses to Rey 3 times in every encounter (despite supposedly being equal and better trained since he supposedly trained under Luke for about 14 years since he was 5 and should have trained under Snoke for another 10). His only kills of named character is old defenseless Han and injuring Finn who recovered after a quick Bacta bath. Hell, during the final confrontation between Luke and Kylo, Luke completely messed with Kylo and basically let himself lose. This is the threat?
If you look at them piece by individual piece, plot holes and inconsistencies can be explained away. But when you look at it as a whole, it doesn’t hold.
