Rules don't cause PVP ... PVP-centric-players cause PVP.
For the most part, people here wanna role play. To some, role play includes PVP ... and in some of these cases they consider PVP a required event when they encounter certain character types. Its all based on the individual (or group of individuals). I fly my pirate through Liberty now and again with relatively no troubles. The Liberty authorities know that I avoid pirating in house systems. They do maintain a watchful eye on me and monitor comms while I'm in the area. But for the most part, while my pirate is flying through Liberty he's delivering food, water and medicine to the poor (namely Rogue bases and such). So ... role play is intact. If I start causing trouble ... the bring out the pwn hammers.
