The logic is just that courts aren't stupid. I've noticed sometimes this tendency in programmers (and in my younger self) to see human systems like computers.

The logic is just that courts aren't stupid. I've noticed sometimes this tendency in programmers (and in my younger self) to see human systems like computers. A court isn't a VM running the law as a bytecode. It's a bunch of humans, and they operate on common sense, too. Often there are gray areas and it's possible to sidestep the law, but you need a minimum of plausibility... if you put a note on textbooks to say "for use as fuel only", then go and sell it to students, I doubt that'll fool anyone. It's the same thing for selling burned CDs with a note to say "for use as recycled plastic only". There's a difference between selling them by the crate to a recycling center, and letting customers buy specific titles individually. The letter of the law may not specify that difference, but that doesn't make it irrelevant.
