If anyone is taking pg's essays as what they they ought to think rather than as what he happens to think, that's their problem, not pg's. I don't think anybody is taking them that way, though; people are just conjuring this up for some strange reason. Some even suggested that HN has this response!
Actually, I think I know the reason. pg writes to maximize brevity and directness. He's always interested in the shortest logical path from A to B. When language is optimized that way, it has a force that can sound like an implicit claim to authority. So his essays land that way with some readers, and then they react with a sort of protest: who is this guy and why does he get to act like an authority? But he isn't—what he's doing is stripping out everything extraneous, and that includes the soft touches that normally soothe the reader—"this is what I think", "your mileage may vary", that kind of thing. He's not stripping them out because he wants to provoke or thinks he's an expert or anything like that. Rather, it's a matter of taste. He likes to make things minimal. The same impulse is behind Bel, or the design of HN's front page. This is someone who might spend weeks getting rid of a single line of code if he was convinced the program could be shorter.
Before I met pg I thought it was impossible for someone to talk the way that he writes. But he does. He's always going for the shortest way to put things. What's clearer in spoken language than in writing is why he does this. It's for pleasure. In person it's infectious, because he clearly does it for its own sake and for fun. It's also essentially the thought process of an essayist: someone on the hunt for just the turn of phrase that makes a point in just the right way, and then moves on.

They might think of something you missed or find parts that are unclear. But I don't think he's looking for experts so much as good readers.
