It solves part of the problem but quickly imposes a tragedy of the commons. These sub-10$ services pay peanuts to the creators. In order to make any meaningful money you have to have millions or hundreds of millions of views. To reach that scale you have to create something appetising to the masses which frequently entails clichés and sub-standard work. I do hear plenty of songs, movies, books rehashing the same old things following a cookie cutter approach.
I do remember reading a twitter thread of creator who sold books and earned a six figure income when a youtube creator chimed in and reported earning less than $300 for more than million views. Not an apples to apples comparison but you quickly see how youtube/spotify would actually create market pressures which discourage people from creating works of cultural and social significance.
In such a world, books like GEB and Piketty’s Capital would never see the light of the day.
