The original of the digital copies do not have any physical value, either. A teacher, a manager, or a trainer (in the world of sports), a musician performing live do not create anything of physical value. That is an arbitrary distinction made by you. Sure, some artists, authors seem to be overpaid. But if they bring in the big bucks because people are willing to pay for their works they create a lot of value for society. What you get paid depends on how much you are making for your employer and how easy it is to replace you.

You do have a certain point regarding copyright after death. 70 years is a long time. But you have given no specifics on how else the artists should be paid.
