I've only seen half of the blueprint cos mines knackered (grrrrrr) but I think what Tyler is getting at when talks about being confident in yourself whether you are good looking or not, is more to do with just not really giving a shit about trivial things such as the amount of money you have or how good looking you are. He's diving for a deeper meaning to your own existence; one where it doesn't matter what you look like, because you truly value yourself regardless of what other people think, which isn't dillusional at all!
One bit that really struck a chord with me was when he talks about his mate, who isn't particularly good looking, but has great success, and Tyler quotes him and say's something like "everyone keeps putting limits on me, so why on earth would I put any more on myself". What a brilliant outlook on life.
