I don't disagree with any of your points, but I don't feel that it's prudent to live life as though everything could fall away.
The sustainability is the bigger issue. Solar charging should take care of the battery / energy scarcity issue.
And I strip any DRM on the books as a matter of course.
I guess what I'm saying is, come the dawn of your scenario, I'd have to buy more paper books.
For now though, I'm revelling in the fact that I have more space in my apartment and that my next house move is going to be significantly easier.
