I used Facebook for a few years, and deleted my account last summer. What I have observed is that, while indeed I have other means of contacting nearly everyone that I was connected with on Facebook, Facebook was (and I presume still is) their preferred means of staying in touch with people. Sure I can call them. Sure I can send them email, or paper letters, or text messages. And for specific communications, that's fine. But for just sharing what you're up to from day to day, or week to week, many people appear to prefer using Facebook, and find other methods inconvenient.
