The flaw is that you depend on Google. You can not trust them at all, for anything. You can use Drive as a redundant fifth backup either for data that you’ve encrypted yourself or for things that you don’t mind being public, but not as the only place that has your data. Things that could very well happen: you get locked out with no recourse; people at Google browse your data; your data gets mined; your data gets lost; Google messes up and other people get access to your data; Google gets a subpoena and those photos that you thought were perfectly normal are now evidence of a manufactured crime.
