Very interesting take on ethical aspects of making money of art.
In my view, what we are experiencing now, is the currency system that is evolving. Initially we humans used barter, then commodity based currency(gold), fiat currency and most recently we see the rise of the cryptos. They are all means of storing and exchanging value, and if something had a value (like streaming a song from an online music service) does it really make a difference if you get paid in gold or bitcoins?
Let's take a basic human need. Food. Neither gold, dollars nor bitcoins could directly be used to fill your stommac. But you could trade their value for a piece of bread. If there is a currency system that everyone agrees on.
Is there really any significant difference?
