That is just a single example from my personal situation and in my own circle of friends, I am not alone in that expectation. We could look at another example, say the increasingly widespread use of mobile payments in China. How about people living in areas without other major services who need to keep in touch with family/friends/emergency services? Regardless of the other situations, you're also making the assumption that I and others can just immediately find other employment. With the current massive number of layoffs, alternative employment prospects are dropping for a hell of a lot of people. So if this is the only job I can get right now, is it reasonable still to say that I can 'easily' give up my cell phone, for the low low price of not having enough money for rent/mortgage and food?
