Perhaps you misunderstand what is meant when people say a theorem “applies”. It means that the preconditions are met (and that therefore the conclusions hold), not simply that the conclusions hold. The conclusions of a theorem can hold without the theorem being at all applicable.
If you meant “Arrow’s theorem is not applicable to any voting system on Earth” why did you object to my statements about PR? The PR issue is irrelevant, is it not?
