It's also just such a leap from what that question ought to imply which is "this is a hard problem, power like that is ripe for abuse, and so we should think carefully about how to implement something like this." Instead, the suggestion is that just asking the question "who decides" should constitute an argument for "nobody, because it's too hard to even try." I absolutely loathe this all-too-common attitude of thinking that social organization problems are hard, and therefore we should never try to improve anything under any circumstances.
