my 2 cents for bounties:
As people said, I think that the bounties aren't placed by ninja villages, they are placed by personal people who hold a grudge against a particular ninja (maybe Asume slept with someone's wife when he was young? that's the ninja thing to do), and probably stack up with time (take Tsunade, for example, she probably made a lot of small enemies during her time as ninja, so if a few of them offer around 10k-100k each, then it gets pretty big), and after a few years in action, people in that profession are bound to step on a few toes.

also, the bounty system works as a proxy for villages to get rid of threats without getting the entire village into a new ninja war.
So who's the asshat who wanted a monk dead?
