Facebook is like a phonebook with everyone I've met. I live away from where I grew up so often contact with friends has large gaps. I don't have everyone's email/phone and those change. To get them once they change I'd need a directory like Facebook. Network effect and low friction is why it's useful but if everyone was on some other platform where I could find them by name I'd happily switch given I mostly use it for messaging and event planning.
