If by 'lose digital citizenship' you mean 'kicked off Facebook' I think that's probably overstating. I got my first domestic internet connection in 1996 and have never had a Facebook account yet don't in any way feel deprived of 'digital citizenship'. Perhaps I'm unique!
I understand that in Italy without a facebook (ie whatsapp) account it is very difficult to live a day-to-day life due to the fact that most vendors (eg doctor's offices) assume all customers have one.
