You are incorrect about the one-view-per-title rule. In the first decades of the Library's operation, one could return to see the same video more than once.
A well-known director (GG) came many times to see the video of the Guitierez Most Happy Fella. He directed a production (renting the same set) and reportedly imitating the staging. He could not be called to account for copyright infringement of the direction since that concept is not legally recognized.,
However, a settlement was reached. I recall at the time, it was reported that even though copyright for the staging was not recognized, CC reordered the scenes in the same way that Gutierrez's Broadway production had, which was considered a copyright infringement of the script because he had no permission to do so. (Gutierrez had permission.) Apparently this provided leverage, though I am not sure how.
This was when the Library initiated the one-view rule. The point was to discourage copycat productions.
Someone below claims that the Caldwell Love Valor Compassion prompted the rule, but the rule was already in effect by that time.
