I agree. I was speaking of the quasars from the more recent epoch though, when the mergers are much less frequent, and the population is more sparse. I was mostly commenting on this because William seemed to be setting up to argue that the close quasars (by this model) must be late forming galaxies, or perhaps something even more strange.
