Not a chance. You can see this with the US Postal Service today, with some people arguing that it should continued to be stripped because it isn't profitable. It isn't supposed to be profitable!
I think the closest we could ever get would be an "old Netflix" approach, where you have to pay a monthly membership fee based on the number of books you want at once that turns a profit.
As for eBooks, I generally find a spot to buy them online (with or without DRM) and either rip the DRM out or pirate them after purchasing. Voila, it's just like a normal book now!
