RP without PvP does and can exist, I've been part of quite a few of these, usually in Liberty, as a matter of fact, although they are usually conducted with the people involved 5k apart and cruise engines full on trying to escape, while they shout at Rex for being a coward and he shouts back that they're nasty shooty people, but it's still RP. There's also some better RP which can happen, from me convincing a molly to continue his piracy on the Kusari side of leeds, to the full blown Treaty of Curcao (which did end in PvP, but not between the sides who were meeting in the first place, bloody indy unlawfuls trying to kill the Queen)
