And be glad the duration is 70+life years instead of hundreds of years. I mean imagine if you bought land or a house and you have rights to it only for 70+life years. After that, your children/descendants would have to vacate the place and it would be public property, perhaps a park. Does that seem okay to you?
Please... copyrights are a deal between the government and authors that in exchange for doing the hard work of creating, the government will offer a monopoly on REPRODUCING the content for a LIMITED period of time. The actual physical copies that the authors create (the manuscripts, for example) are still theirs to keep FOREVER. Just like me and my house.
