It's a calculated risk. Chances of this happening to any given person so far has proven to be almost infinitesimal, so people (rationally) don't care and treat GMail like they treat electricity.
But yes, if this indeed happens to you and you were depending on Google services for your work and life, you're completely screwed.
Sometimes I feel afraid of this happening to me, but I don't know where to move some of my data to, as every other mail/calendar service I know sucks hard in comparison to GMail and Google Calendar.
Enterprise apps accounts are pretty cheap compared to your average business expense. Not speaking as a googler, just a concerned fellow hacker. That might not perfectly insulate you from risk, but I guess (again, without any internal knowledge, I don't work on this stuff) that it cuts it by another factor of ten or more.
