I didn't want to write a treatise here, but since I have five minutes, I will add:
In your example, you say that you put X time and effort to "produce" the specific arrangement of information that you think is original and useful and that people should pay to receive from you. But what you really did is two separate things: you "came up" with the arrangement, which resides in your brain, and THEN you "produced" a physical object supporting it, which is what you can really sell.
When the information is out of your brain, it's immediately readable by others (that's the whole point, right?), and you are accepting that anyone who can read it can possibly reverse ingeneer it, or straight out copy it. It will all depend on how reversible the arrangement is, and on which specific format you decided to put it on. It's not by pure chance that information on an electronic support (a mere sequence of binary code) is at the same time the one that allows for widest and cheapest distribution, and the easiest to copy.
If you don't want your latest novel's of your music album's "intellectual property" downloaded on a P2P torrent network, stick to reciting them orally in private closed-door sessions where you can make sure people attending cannot bring in recording devices.
