I think starting out with a legit business could be the way to go. It won't be all PvP since there will be instances of NPC pirates appearing here and there in the game. We could start out doing the in-game generated missions and then offer our services to other players that aren't with groups. We could do something like a merchant ferry group where we offer a larger group of single players to piggy back with us to other systems. They pay a small protection fee.
I think FITES pirating as an org would need to be done with a certain amount of risk vs reward consideration. Maybe small guerrilla pirating against larger factions that are troublesome.
If the whole of Star Citizen were condensed to the DS9 universe... we could be the Quark.
