We need more examples?
Seriously, though, there are options in between keeping copyright as it is and removing it altogether. Shortening the term is one. Mandatory mechanical licensing is another (that is, allowing people to make copies for a fee set by the government or a nonpartisan board without requiring permission from the copyright owner, who does, however, receive the fee—the trick is setting the fee at a level that makes it reasonable for the average person making a single copy, but still high enough to make it unattractive for corporations churning out millions of them). We also need to overhaul how derivative works are handled, and some aspects of trademark law.
