Boiled down, his main point is:
The rules of supply and demand don't work in a digital world, because the supply is unlimited. You don't fight piracy with weapons. You fight piracy with cost and convenience.But there's a lot more to it than that. Required reading if you're interested in publishing at all.
If there were a central hub, where you could easily search for ebooks and get them at a reasonable price, there would be no need to pirate books.
