You want to restrict information to people able to purchase electronic devices and data subscriptions?
Guess what libraries provide? Free book and computer access. Nothing changes.
Paper is an amazing medium for transmitting information: cheap, battery-free, easily copied or lended, transferable, DRM-free, non-proprietary, no monthly subscription needed...
Now books, easily copied?
When's the last time you tried to share a copy of a book with a friend? Or did you buy a blank and copy it by hand? While that's a laudable example of dedication it's not exactly easy nor convenient.
Cheapness is likewise debatable, printing out a 300-pages book is fairly expensive.
Most other concerns are concerns only if you use broken-by-design sources.
