Ah, but Google are doing NOTHING (other than writing a crappy policy) to enforce the use of your actual "real" name. You could be "John Smith" and they would in all likelihood never even NOTICE (the downside to you is, of course, that people who know you are looking for "sparkleMonster" or at a PUSH "Janet Jones" but certainly not for "John Smith"... that could be an upside too of course if what you want is real anonymity, and you can always tell the people you care about through some other channel).

And at the same time they are banning people whose actual, honest-to-god, on-their-passport "real" names don't fit into Google's notion of what a "real" name is allowed to look like (I know numerous people with such names, and my social circle isn't even all that diverse).

My provisional conclusion is that Google are either damn stupid, or their real desire is something entirely other.
