I disagree. Most people understand the broken window fallacy. This book shows them how that same reasoning applies to other things like price controls, protective tariffs, minimum wage laws, rent control, etc. If you understand the broken window fallacy, you'll be forced to agree with the other arguments presented. It's taking something that people implicitly believe and making it explicit. That's the most powerful educational tool there is.
Of course, that requires intellectual honesty. If people are just being closed-minded then your analysis holds.
If you were a communist you would say exactly the same about the arguments made in the books communists like. And of course you're now thinking "but the difference is that I'm right", just like anybody who's chosen an ideology would.
