It's not just about seeing people. It's about having deep connections and shared experiences. Eg: one of his friends has a life crisis and just needs to talk to someone. Are they going to hop on a train and track this guy down, or will they go see one of their other friends? So he will miss out being the person someone turns to, and these are the defining moments for long lasting friendships. Again, probably fine for a while, but if it goes on too long those existing friendships could fade away and he could miss out.
