With regard to your first point, I don't think that's what the author is describing: "Once all of the votes have been cast, you pick one voter at random and use their choice" It's not a matter of representation, which would not only be OK with me, but necessary if we claim freedom of speech. The author is describing a random dictatorial mandate weighed based on constituency size. Maybe I'm completely misunderstanding this...
