Not really. […] There are well over a hundred in reality, but less than a thousand, which when you divide by the 1B+ ethnic Chinese (Han) in China alone, gives you a lot of namespace collisions.

Well… I would say that less than a thousand names is indeed, “a very limited pool”. The article you linked to mention some names being used by around 10% of the population, for instance.
Actually, when I said " a very limited pool" I believed it was less limited than that, not more.
