digital music is not artificial scarcity, because it's not the copied bits that are the resource, it's attention. we only have so much time and attention for consuming media, and only so much attention and memory space in our brains for keeping track of where to find it. large budgets can easily dominate these channels and limit the average person's apparent choice.

this is what I mean when large players would outcompete smaller players in a digital marketplace with no copyright. the only way for this to work would be with a benevolent neutral 3rd party managing the marketplace, like Steam, so users can easily see when a large player is cloning a smaller players work - but even then it still depends on the good will of the general public to prefer the "original" artist which is not guaranteed.
