Unfortunately I think this is a problem with many of his essays. They often present a very specific argument with reservations, which makes the argument very hard to disagree with since you have to argue relevance which requires a lot more insight. It's therefor taken as truth by the readers, even if the original argument don't support their conclusion. In general I think they should be seen as opinion pieces rather essays. I have a hard time seeing many of them being up to e.g. basic university standard.
