It takes a lot of effort to make on the fly changes like this "fit". Much more than it would to not come up with new things for the story and just stick to only the things you already came up with in your head for the first one.
It really is being lazy to act like Lucas' solution to Obi-Wan's apparant contradiction doesn't make any sense.
I'm not saying you have to like it, but it does make good logical sense the way Lucas did it.
The whole saga is about points of view, and this is one of the showcases of that in action.
How could you possibly not appreciate that?
