the overall message is good however, plus you don't have to view it a set of laws more of as guiding principles for the game
i take your point that referees need to be respected so that we have them coming out to take charge of games in the first place, on the other hand there's more to it than that - rugby is a thinking man's game of hard, yet fair aggression and discipline, restraint and the referee symbolizes this balance and plays an important role in our game, he is crucial - that doesn't mean he has to impose himself on the game, refs should be respected more, regardless of whether they're primarily needed to get the game on - personally i respect the ones (especially former players) that go out of their way to officiate games and give back to the game.
as far as the "tuck your shirt" in stuff goes i wouldn't take that all that stuff literally
