The problem many people have is convenience. For example if you are forced to use Facebook in order to log into a Hotel Wifi (as I recently was) then you have to say "I don't want the Wifi more than I want to log in with Facebook". It's not an essential.
Or, it might be more difficult to spend the effort keeping in touch with people on a personal level, but it's not impossible. It just doesn't have the convenience that Facebook gives. But it also doesn't have the costs.
I'm not trying to convince anyone. But I do find it increasingly interesting (as I pay more attention to it) how many people confuse 'convenient' for 'essential'.
