Actually alliances like 1up, LCH etc only can grow that easily in the beginning because nobody knows their coords right away.

If coords for alliances would be public the major alliances would surely start fighting each other a lot earlier.
Also people from the top alliances would no longer need to fake nick, which would lead to a probably much more friendly atmosphere on IRC and galaxy forums. Fake-Nicking people rarely get too much in touch with their galaxy, only as much as necessary.

And let us face it: smaller alliances members will be bashed once they are decent sized targets, no matter if their alliance is known or not.
