> End copyright at death of creator might give people some ideas on how to deal with ideas of canon. Problems with canon are possible regardless of copyright, and changing copyright durations does not add or remove these problems. If it is made clear that any changes or new works made due to modified canon are not the work of the original (now dead) author, then this may mitigate some of these problems somewhat. Abolishing copyright makes it easier to improve too, since then if someone thinks they have a better idea (which might or might not be true, but it can be judged by people after it is done, and it is OK if people do not all agree) then they can do it without a lawsuit. (Just, you will have to be clear than these are now new works rather than the original works. The original canon is not to be changed, but you can make up new ones which are based on them.)
