What exactly are you implying? Perhaps the author is simply not a libertarian. Not everyone who identifies themselves as "classically liberal" is. Some people others would describe as "conservative" use that label also. I also don't see what using that term has to do with the author's debating ability. If anything, it's my experience that most people who use "classical liberal" have read all of those books and prefer to root themselves more in Burke's premises.
