Personally I think it all boils down to 'just because you can, it doesn't mean that you SHOULD' .
Or maybe it's that everyone wants to be the heroic battleship captain who single-handly saves his/her country from the evil enemy.
Bah, I'd rather be the evil enemy anyday, much more fun.
You get loads of perks too, like knowing that your life insurance will be paid out (to someone), heroes lining up to get shot/maimed etc, plenty of eye-candy who only like you cosyour in power/charge, the chance to give evil laughs whenever you feel the need etc.
EDIT:
Yeah,and then how many people will NOT be RPing as an outcast, corsair, order, house pilot?
