All of the reasons you listed for peer review are valid. The broader point is that peer review can happen outside of academic journals, and nobody has an incentive to submit to them who isn't trying to play the academic prestige game. For a significant example, see the history of Perelman's proof of the Poincaré conjecture.

Good, I just wanted to point out that peer review isn't primarily an arbitrage of truth, it is also to make sure the exposition is nice to read. When you get a reviewer who actually cares, you receive lots of feedback that isn't related to the correctness of Lemma 3.14.15 and stuff like that.
