Copying has a specific definition under the law. Physical lending of books does not come close to meeting it. Applying any of the fair use tests to physical book lending thus does not make any sense. It's like applying the Central Hudson Test to my cooking of a grilled cheese sandwich: it's lawful, the government has minimal interest in regulating it, none of that matters because my sandwich isn't expressive.
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".

No, no, not at all.
In this situation I just want to change the definition of "copy" slightly.
(And to point out that slightly different definitions of terms would make libraries illegal. There's nothing special about the current definitions. In particular they're not the most straightforward definitions at all. Again, none of this is about radical change, just looking at where small tweaks would get us.)
There is no reasonable definition of "copy" that would make the lending of a physical book a copy. The word "copy" literally exists to differentiate other actions from that action.

But it could count as distribution. Copyright covers that. Library style distribution could be just as illegal as CDL style copying, by barely changing anything.
The point is that yes, digital items get treated differently by the law because using them requires "technical" copying. Moving them requires copying, using them requires copying, lending them requires copying. The law as written means that digital works will give their buyer far fewer rights than identical physical copies of the same. And yes, that's precisely why the current law is bananas, because it turns digitization into an excuse to enclose the commons. But I have no confidence in the courts to stop it, because that's not what courts do.
Except when it is. Laws are not computer code and it's precisely the court's job to interpret how they apply. This can include overturning previous interpretations. For examples see the recent ruckus about supreme court decisions changing what people interpreted as fundamental and accepted rights.
It is however not much a stretch to say that someone reading a book and committing it to memory is making a copy not inherently different from the "copies" being made when viewing something over the Internet. Now if you go and lend/sell a book after reading it you still retain the copy in your mind. Yet somehow that is legally fine.
