Good luck. The only reason the library system exists at all today is that it is grandfathered in. Can you imagine someone suggesting a government funded system of free lending of for-profit materials in today’s copyright climate? They would be lucky to be just laughed out the door instead of sued by the publisher’s lobby just for suggesting such an idea.
The shame is that the public library system is a proven good. It’s one of the great equalizing factors in the world, and there is absolutely no chance of anything similar existing in today’s world because copyright holders have all of the power in government. The closest thing we have is the free software movement, and even that still struggles for legitimacy.
