> It you think copyright should be shorter to everyone, then inheriting something valuable shouldn't be a thing as well?
inheritance has nothing to do with copyright. Financial assets are not monopolies. Copyright is only a valuable asset because of the granted monopoly on copying/distribution.
Therefore, to reduce the value copyright has (as it currently does seem to have too much), reducing the granted terms should be sufficient. Like patents, a good 20 years seems like a sufficiently long time to recover cost of production, while letting people who are currently alive to produce derivatives of it afterwards.
Why you want to reduce value of creative work, but not a value of other assets? I think copyright should be as long as ownership of any other asset.
If I spend $20m on building a house or creating a computer game, why house can be inherited indefinitely and creative work is not? I would have a monopoly on this specific building and on this specific creative work, but anyone is free to build/create anything else.
If J. Rowling created Harry Potter universe, why her family can't own it indefinitely? We somehow accept this notion for other assets, but treat copyright differently.
p.s. creative work is more valuable as it has something that money can't buy (authenticity, taste, sincerity, etc)
