The writing style was terrible, as every third sentence seems to close with something like "and this inevitably leads to socialism and serfdom, and eliminates freedom". Only a dozen or so pages in and I was thoroughly sick of this device, as it's becoming clear that's his main and just about only argument -- extreme repetition.
It's a short article padded to a book length rant that anything less than total laissez-faire market libertarianism leads to slavery, serfdom, social democracy, socialism, nazism or communism (He appears to understand no difference between any of these). That any tiny government plan, regulation or service must lead to totalitarianism and blackshirts.
So my memory is also of finding it hilarious, I suspect for very different reasons. I also remember being left completely baffled as to why it ever got to be popular. :)
