Honestly a viable system would very much depend on the socio-economic conditions. Without falling into the political, I think I am still within the rule that pointing out that an artist making, say, 1,000 USD per month in the current condition that would be reduced to 500 USD per month due to increased AI competition would be in a very different situation depending on whether he was living in a high-expense country (and living in his car, from what I understand about the cost of living), living in a country with a very high level of social security (barely making ends meet, but not starving by far thanks to the subsidies and social discount he'd get) and living in a least-developped country but able to compete on the worldwide market through the Internet, and where such a sum could be twice the average salary. All would suffer from the reduced income source, but not in same proportions, and the willingness to adopt solutions would be very different as well.
