> To the best of my understanding society had a culture 5, 50, 500, and even 5000 years ago. The current availability of books published last century is actually smaller than the current availability of books published before that. So there is actually a bit of a cultural hole from the 1900's because of materials are still in copyright and not published by their owners. Often it isn't even known who is the current ow…
Not having documentation on what culture was X years ago is different from there being no culture X years. I don't think your first example is relevant. Copyright exists to serve the public. I think it largely achieves that goal. There are fair arguments to be made as to when copyright/patents stop serving the public interests. I don't think DRM as an enforcement of the copyright laws nullifies the protection already…
I, however, agree that copyright serves the public and largely achieves that goal. But I think it did so better in it's original incarnation. Big money interests have shifted copyright in absurd directions. And I honestly don't care if Disney retains the rights to Mickey Mouse forever but in lobbying for that right they've dragged along everything else. So now it's impossible to reproduce other completely unrelated works.
A big one personally for me is old video games. I grew up in arcades and I love going through MAME and playing obscure titles that I often don't even remember until I start it up. Sure, if you want to play Pac-Man there are lots of legal options but outside of that a huge part of 80's culture is illegal to own.
