Encouraging creation is part of the deal, preserving culture, and enabling wider education were also parts of the deal -- Queen Anne (or her advisers) seem to have really valued the availability of literature for the people (or at least the priveleged people with access to the BL and Uni libraries).
eh, but copyright as it stands now, decreases the availability of literature (I mean, aside from how it encourages creating it, which is super important, of course.) so those things couldn't have been reasons for creating copyright law as it stands in the US. (an interesting side effect, as a person willing to spend money on books? It's a lot easier to get a good e-book of something still under copyright than of some…
I don't think your analysis stands, there was a deposit system in USA too so that all copyright books were deposited at the Library of Congress. In order to get your copyright you had to place on deposit two copies that people could, with access to the library, view and which would be preserved even if your work only had a short run and other copies were lost.
