As you say, it's not perfect, but it would absolutely help us preserve culture beyond what is still classic 75+ years from now. We have lost the vast majority of silent era films and more historical films will follow since it's illegal for you to save them to digital format without the explicit consent from the content creator. We won't lose Casablanca or The Seventh Seal since they're preserved by historical archives and companies can still make money screening them but TV-movies like Star Wars the Holiday Special is only being preserved by illegal means because nobody bothers enforcing its copyright. Sure, that movie is an abomination, but film historians 100 years from now would presumably want some proof that Lucas made it and that it really was the first appearance of Boba Fett.
