I need some reasons...

Tolkien's use of his languages in the book went deep into the very heart and meaning of his stories, so if you do manage to gain a working knowledge of the Elvish languages then I can only see that as a good thing. You would be able to recognise roots in words, particularly in names, which may help in understanding the history and nature of those characters a little better. The languages are all part of the story, and I admire anyone who has the ability to learn them. Yes, it could be seen by some as 'going too far', but then if you are interested in anything then why not pursue it as far as you wish?

That has to be urban myth! It did make me laugh though. A few weeks ago at work I admitted I didn't have a passport and when they asked me if there weren't any countries I fancied visiting I only half-jokingly replied "a passport won't get me to Middle-Earth". Still, it was early in the morning and I hadn't yet had my second breakfast...
