I'm not sure why it's a problem. Google+ isn't that kind of website to me. Reddit, HN, etc. are really in a different class of websites and should be treated as such. Google+ is like my Address Book. I want real names, because they look nice. I should not that (in my mind) this doesn't make "JK Rowling", "Mark Twain", or "Jon Stewart" unacceptable. "rms" or "natesm", on the other hand, aren't the sort of thing that I'd want to see on Google+.
Similarly, I have Adium set up to display real names and real pictures instead of ugly AIM screen names. I don't talk to ladygagafan05, I talk to "John Smith".
