You are forgetting that artists have to pay for equipment, eat, have a place to live, etc.
And then there is the cost of a renting out a studio, a good sound mixer, additional musicians to play parts that your main band may not be capable of, etc.
The cost of reproduction may be close to zero, but the cost of production is most certainly not dropping. Technology may allow some genres of music to be one man bands, but that is certainly not true for all music genres. Orchestras cost money.
I think we can discuss that problem when it actually becomes anything other than a fantasy. There are solutions to the "artists are literally starving" problem, but there is really no sense considering them while artists are still flying around in private jets.
Sure pop stars are, but there are hundreds of thousands of artists who aren't signed to big labels.
I really don't care one way or the other about any artist who plays on the radio. I want to ensure the artists I listen to are able to continue making music, therefore I buy their music.
