I’d argue we have countless of digitized books, photographs and movies from way before 1969 that we wouldn’t get access to in physical form. They might not be our individual personal copies, but they’re there, actually accessible. To your point, I am strongly for enforcing DRM clearing after the copyright expires or the entity owning them goes under (it should be required by law IMO). I also think collectively we have a fighting chance to preserve copies as long as they’re free of DRM.
