I agree with jslim419. Any society that lasts any amount of time at all in the real world has laws, and one of the first laws created has to do with theft. Eve may be the "wild west" of space, but even the old west had laws and enforcement when you came into town.

As for the "it's only a game" argument, that money didn't magically appear in player bank accounts. It was earned -- often through a lot of very tedious repetition. When you steal from someone in-game like this, you are effectively stealing their time.

Games are supposed to be fun. That's why we play. But when one person's fun comes from the destruction of multiple other people's fun, that is a bad thing for any game that doesn't want to spend its lifetime in niche status. Sooner or later the wolves have driven off all the sheep, and all that's left is other wolves.
