I admit I was a bit disappointed by the end of the article. But I don't think it was strictly an appeal to authority. The author is evidently a very good writer, but he might have done a better job at summing up a conclusion. It's very difficult to tell just what point he was trying to make. He never even said just what his inputs and outputs are in his housing model. Even if he is saving that for a later article, he should have at least mentioned that.
