Continuity mistake: Near the end of the film, during the close haul battle with the Endeavour, the East India Trading Co flag on the back of the Endeavour changes during the scene from initially being blue with white letters into white with black letters. This is first noticeable during the last overhead shot of the ships before everyone yells "fire!"
Continuity mistake: When Elizabeth is giving her speech about the crew of the Pearl, her arm is either straight or bent depending on the angle. (01:56:00)
Answer: From the point of view of the Dutchman, Bootstrap is dead enough to serve on the ship. The idea is that Jones rescues people who would otherwise simply have drowned and makes them serve on his ship in lieu of death; as such, they can be considered technically deceased. Elizabeth has been into the Locker, yes, but with the demise of Jones, the Locker may not even exist any more. Will's task is to escort the dead into the afterlife, not the Locker - while Elizabeth survived the Locker, the afterlife may be something entirely different. The rules regarding the Dutchman and the duties of her crew are never spelled out, but it seems that, no, Elizabeth cannot live on her.
