I agree it's not perfect but that's still several steps removed from "Billy is one of us, he should get that tenured position" and, as this article shows, it requires openly unethical behavior, which others can recognize and eventually prosecute (even if that isn't being done often enough).
It's almost like saying "well corruption happens anyways so why do we even criminalize it and have public hearings? Just skip those bits and openly auction votes instead".
