Not really, no. Though I would argue if Google disappeared tomorrow, as a private person you would probably do mostly fine. The point being, that your dependence is most likely not that strong actually. Unless you got important mail arriving at only your gmail mailbox. That would be dangerous. I lost several good accounts on other websites that way in the past. Now I don't register anything useful on gmail addresses any longer, in fact don't actually use gmail any longer, unless I still have some old accounts that I still didn't migrate away out of laziness.
