Unlike physical goods, information can flow and be copied freely at a fundamental physics level.
The electricity and silicon required to make this happen are not free, on a societal or physical level. There is a tangible cost to this transfer, even if you're ignoring the social construct of copyright.
I think this issue comes from a misunderstanding of "free", possibly conflating it for "trivially easy".
Rather than develop a system that rewards digital artists based on how much something is used for free
Feel free to come up with such a system. I think you'll find that a rather difficult task.
It's exited before any of us currently alive, so that's a pretty absurd notion. Unless human culture and history ended ~300 years ago?
