Please look at what I'm actually saying instead of snapping off replies that don't address my point. (And yes I edited in another couple sentences but the part about libraries not copying was in the original version of both those posts.)
(You're fine editing; I edited too, just for clarity).
Let me try making my post a list of bullet points.
* Libraries are allowed because technically it's not copying, and otherwise would be very illegal. Agree or disagree?
* Controlled digital lending is only copying on a technical level, not in the traditional sense where more than one copy can be accessed simultaneously. Agree or disagree?
* If CDL could somehow remove that technicality and do pure digital transfers, it would be fine. Agree or disagree?
* A better version of copyright would ignore that technicality. Agree or disagree?
If your whole point is that we could tear down all of copyright law and replace it with a system that allowed IA CDL, then, sure. We could do a lot of things. I'm not really here for that argument (because there just isn't enough to nerd out about in it, not because I have any problem with the exercise).
But as for the law as has existed in the United States for the last 50-odd years, I'm reminded of the words of a young Baltimore entrepreneur, who infamously said "you want it to be one way --- but it's the other way".
