Well, simply that, a false positive on the drive gets the whole Google account removed. Not just the drive access, but all your past mails (and the future mails you will receive because you are unable to tell others that you had to change your Mail ID), all other accounts you made using said ID become harder to access and same for other Google services (paid or not) that you might be using at that moment.
And you can't even send a user data retrieval request.
