Jack Sparrow complains of the mutiny against him and the taking of his ship, but who enforces him being captain or ownership of the ship, if not the crew itself? So why would he talk in such terms?
I've read that with pirates IRL, they would vote on where to go and what to do, and a captain would be chosen for times of battle, and if the captain did poorly, they would just pick another, no big deal. And the bounty would be split mostly equally, with I think a bit more for the captain. A mutiny in the Royal Navy is a mutiny because the Royal Navy says so and enforces rank and ownership of the ship (or with the help of other government forces), even if, say, the captain doesn't complain about being left on an island.
It seems in the movie it's imposing norms from their own society on a culture which had no such devices. Or am I missing something here where a mutiny on a pirate ship would somehow be applicable? Did the movies make any sense of this that I missed? Like saying there was some pirate organization that made such actions punishable? Or did someone at some point at least point out the ridiculousness of his mentioning mutiny and claiming the ship as his, whereas it's obviously the whole crew's ship and decision (something similar could have been said to Barbossa)?
