If they did that then they could also implement artifical gravity.... but that has never been part of the elite universe.
The only thing NOT within the laws of physics, as they are currently understood, in the game is the ability to travel faster than light and to make the jumps between stars. But without that there is no game.... the design of the space stations is based on physical laws, so why not communications. Finding a method of communication that is consistent with the rest of the game preserves the sense of immersion, which is of huge importance to a lot of forum members, judging by the number of posts about it.
Actually, faster than lightspeed electronic communication is already implemented in the game.
The Bulletin Boards and Galactic Market would never be able to stay updated otherwise.
