Depends, if you can live as a hermit, then maybe yes. But my circle of contacts for example communicate with Facebook only, and I am already a not social person, if I deleted my Facebook I would spend months before getting. Invited to a party or funeral
It's impossible to have friends that don't use facebook?
It would seem that Facebook is 'required' because you see some requirement to interact with people that won't talk to you in any other way. That is also a choice you made.
Currently what I do is move as needed to get money as needed, and the places where I ended so far everyone else as only passing through too, so new friendships don't have the chance to form.
