It's just that the flute is required to get past Snorlax just to make navigation of the Kanto region a bit easier. Also Snorlax is a nice Pokémon to use if you ever get to catch one.I know the flute isn't the reason for going in game, but thats the purpose of the quest. like you have as little reason to be in the tower as the rival.
But it was nice but at first weird for me to see Snorlax finally stand in X and Y in battle.
