Paper books are fairly easy to spoil even inadvertently (just spill some crap on it - a cup of coffee that a laptop or a tablet will likely survive fine can easily ruin a paperback).

You can get digital books without DRM. And if we don't pass laws like DMCA that conscript the entire power of the state to enforce that DRM, it wouldn't be viable anyway. Indeed, anyone who has seen #bookz knows that technical viability is lacking already, and it's only the legal regime that keeps things the way they are

e-ink is just one technology among many available options for reading digital books. The beauty of a digital book is that it's not tied to any particular device, so you can pick whatever tool is most comfortable for you to read that particular book in the appropriate context.

And we have so many other things that need power already (including, say, lighting, so that you could read those paper books whenever you want) that it's kinda strange for that to be more than a very minor point.
