Ok, but RLM isn't debating whether or not Anakin, on finding some pieces to a protocol droid, should or shouldn't have gone ahead and put them together. He's debating the storytelling merit (or lack thereof) of using this as a subplot. The issue isn't so much whether or not Anakin, if given the opportunity, should've build a protocol droid; it's whether or not George Lucas should have written that into the movie.

Subplot?! And why shouldn't he have written that? It doesn't hurt anything. The problem is that you (and/or RLM) seem to find a problem that a protocol droid can do chores. It's like hitting a strawman.

Because there is a better way to have written it that makes much more sense!
