When you say "no one publishes public domain works as though they had written them" - do you mean that nobody is publishing, say, Tom Sawyer, and pretending that they wrote it?
Yes. This is one of the concerns I hear authors express. They're worried that they'll write something great and someone else will just slap their name on it.
I don't think it's immoral to "pirate" content, but I make an effort to respect the wishes of the creators and compensate them for content that I value. If it's someone like Saifedean, who doesn't believe in IP, then it's just a matter of deciding if you'd like to support him financially.
