I don't think so, to be honest. The context is important and, atleast to me, it seems he makes a difference between "Nick Szabo" and his pseudonyms, here:
Another big problem I see with pseudonymous reputations is entry. If most people are blocking posts from new pseudonyms, how does one get a new reputation stablished? I've had several years to establish a net.reputation for "Nick Szabo", and it might take a long time for any of my pseudonyms to catch up.
