This is already happening. I bought an album(Requiem for my friend by Zbigniew Preisner) from bandcamp couple years ago. Now i wanted to buy a new album but the artist is not publishing lossless music on bandcamp anymore. It's all the big streaming providers.
With my band, we have experienced though that there is (should say was, 2015) not enough visibility, so we opted for big streamers which ripped the money off us, but allowed us to be heard more widely.
