I’m not sure why people believe that artists selling copies of their music being a viable source of income in itself is something that’s necessarily critical and/or a moral imperative to preserve. Humans made music for thousands of years before technology made that possible, and after some decades technology has now made that particular business model less lucrative (it’s now very easy and basically free to share essentially unlimited copies of a piece of music, which has tanked the monetary value of such copies)
As long as music is being made, I don’t think it’s a disaster for society that some artists’ preferred way of making money isn’t so viable anymore (if it ever was - what percentage of acts were ever making real bank selling albums?)
