You don't seem to be familiar with Zooko name systems. With a Zooko type
name system an arbitrary key will simply fail.

You are describing the certificate authority system, not the Zooko name system,
which *is* self authenticating.

With the certificate authority system, the registrar can confiscate NewEggs
good name, or anyone of a thousand certificate authorities could steal it for a
time, which typically takes the form of a man in the middle attack.

With a Zooko name system, they cannot.
