Why stop the hyperbole at public libraries? TPB is the world's most efficient Walmart too because Walmart has per-item and per-person overhead that will never compete with "click this link".
It's the most efficient two way mission to Mars as well when you really think about it: no rockets, no loss of life, and all the latest movies!
Who is being hyperbolic now? It's easy to see that TPB accomplishes few things that Walmart does (such as distributing groceries) and almost none that a Mars mission does (other than serve as entertainment). It's also easy to see that TPB does accomplish many of the things that a public library does, such as offering access to copyrighted works and helping in finding the work you're looking for by maintaining an index. Did you really not see this or were you being disingeneous to make a point?
