There are very few Swedish author who make a living being just an author. The basic premise for copyright is that if you take the time to make something, you get exclusivity for some time. Because creating things will hopefully benefit society. I can see how some time of exclusivity can benefit creation and distribution of certain works and therefor also society, but I have a hard time understanding how exclusivity until 70 years after the authors death benefits anyone.
