Because you eliminate a whole host of potential endpoints for the messages.
Email is not usuually a one-use mechanism, for two people to carry on
an anonymous conversation they must both be registered in this database.
This makes traffic analysis of such a system a lot easier. The disadvantage
of not registering users is that many people may recieve unwanted messages,
this problem should be solved at the recievers end. Even this junk email
which is filtered into /dev/null by the recipient adds cover traffic for
the other messages on the system.
