Clearly you're up against someone who doesn't know what he's talking about. While I can see a temptation to make him acknowledge that he's wrong, is it worth the effort? Saving eight quid if the cost is hours spent composing emails and getting wound up by obstinate twits at Yamaha doesn't seem like a good return on anyone's time to me.
Change it now if it bothers you, else just get in the habit of giving the back wheel a spin when the engine isn't running, if you hear a chink-chink noise the nut's come off and you need to replace it, otherwise wait until the chain and sprockets need changing and do it then.
