"From my view, if there were a good technical way to make electronic book sales much like regular book sales – if you want to give away a book, you can’t do that and keep it as well – I would cheer for DRM. On the other hand, if DRM makes life difficult for paying customers, that’s not good."
This is a thought experiment which I’ve posed a few times: if there was a DRM which which allowed consumers exactly the same "fair use" rights that they have at present, would you support it?
I’ve yet to get a really good answer from anyone in the anti-DRM camp. Mostly, the answers attempt to claim that such a system isn’t possible, because it relies on software being capable of understanding the intent of someone when copying it (are they copying for personal use, or to pass on?). But in books, things are much clearer than in music: there is no fair use right to copy an entire book, even for academic or personal use.
I actually have a theory about this, but I’ll get to that over the weekend.
