I would instead reduce the duration of copyright protection. Not an expert by any means, but my gut feeling is that in the case of art like books, movies, songs, videgames etc. the right-holders make most of the money in the first 10 years after release. If you're interested in a book, movie, or videogame, you will not wait 10 years to get it for free; you would still pay for it. So I think the duration of copyright should be reduced to circa 10 years, maybe 20 if we want to be generous to the right-holders, but no more than that.
