I just don't find any of those reasons compelling enough to make such a substantial change. Luke only ever visited Ben's house once, and Ben was only there taking refuge and watching Luke, hardly a "place of power", as opposed to other places he's resided.

I think all this circularity is very contrived. It can work in some stories, but Jedi is already too much of a rip off of Star Wars, so I think adding to that is just not a good idea. Why can't the conversation just take place on Dagobah?

There's just no reason to move it, unless you want to make a change for the sake of it.
