Many authors do some of their best work late in their lives and it would be a sad society if we stopped funding the art projects of those who got ill or aged because of inability to generate profits from them. The right interval for copyrights is larger than the zero years after death that many advocate for. It's certainly less than 75 years after death though, so there is massive room for improvement.

Perhaps "Life, or X years, whichever comes last" would be an appropriate balance. We can, of course, still argue over what the value of X should be.
