In the end, he may be an "exception" but he's actually WORSE off for it.
Why?
Because he's going to have much more difficulty changing his ways. Guys that don't have looks going for them learn pretty fast that they need to approach girls and develop something of a personality if they ever want to even get a DATE. Your friend just has to wait for girls to approach him--in his eyes, this is normal.
If he remains the same, he is going to find that every single one of the girls that calls him "hot" is going to be plagued with buyer's remorse in the end. He is not going to be able to keep any of these girls except for the low quality, domineering ones that will turn his life into a living hell. A guy that is unable to assert himself will usually wind up with an aggressive, selfish woman that takes the lead in place of him.
Yes, looks matter if all you want is for random girls to approach you and call you "hot." Being good looking will give you a wider margin of error in pickups, too. However, a good looking AFC is still an Average, Frustrated Chump.
My own experience: When I was in my teens, I was decent looking enough that attractive girls would approach me or tell their friends that they thought I was cute. At the time, I believed that that was all I needed. Wrong! When it came down to it, I was unable to take the lead on the interaction and killed the attraction. Then, in my later teen/ early twenties, I was able to fake pretty decent outer game as a result of reading this kind of website, and started laying girls---the first 3 of which were one night stands that never returned my phone calls again. Why? Because inside, I neglected my inner game and was still an AFC. It wasn't until age 24 that I finally got myself to a place where I was doing the dumping. Placing the focus in my life on myself rather than girls, together with "spinning plates" really helped get me there.
Good looking or not, there is no "exception to the rule." You MUST have strong inner game and good outer game/ social skills to get and keep girls interested in you. Somehow, that stuff often comes easier for less attractive guys who learn to compensate early on.
