Interestingly, this is another way in which MM's verbosity is a defense mechanism: It's virtually impossible to make a detailed critique without engaging him at equal length.
I'll mention one specific critique, which is what originally twigged me that something was off: MM constantly introduces special definitions that are close, but not quite, what's commonly meant, and then proceeds to use those definitions for 5 or 10,000 words. This is a form of rhetorical sleight of hand that's suspicious in an of itself, and MM demonstrates this in the linked essay:
"But here at UR, we are operating under our own special theory of money, which I have modestly dubbed MoMT (Moldbug Monetary Theory). If you know and believe MoMT, the leap is obvious. In the conventional wisdom, it's not obvious at all."
He does this sort of thing constantly. Besides investing a lot of time in reading even one of his essays, you must spend a lot of mental energy tracking all his off-by-one definitions of slightly uncommon terms. Again, you have to buy into Moldbugism to even start judging it, which is part of the trap.
Edit 1: I've upvoted you because I think yours is a fair response to my attack, while Tav's cry of "ad hominem" below is mistaken.
Edit 2: Moldbug's comment history here is interesting, in part because it demonstrates that he's very capable of making a concise point. Why was he banned? His karma looked okay.
