Arrow's theorem is nonsense that has set back election reform by decades. Because in any realistic scenario, "irrelevant" alternatives are never truly irrelevant. That is, Arrow's IIA assumption is simply not desirable or relevant.
Once IIA is relaxed to a sane axiom [read: abolished almost entirely], there are multiple methods that work like versions of STV. Besides, Arrow never applied to ordinal voting methods like Approval (which is OK) or Range (which I strongly dislike for other reasons).
