I don't care for it, but so many people I know use it I have no option.
You do have an option, no matter how many people whom you know use it. Your argument is for the convenience of Facebook, not the necessity of it; you could just as easily use the phone, email, post, or even a personal webpage to stay in touch with your remote friends and family. Perhaps you wouldn't be able to reach out to however many dozens or hundreds of "friends" you may have in your network online, but there's a secondary argument there, hinging on the definition of friend.
