Agreed, but therein lies the problem. The markets for our needs are still markets based on scarcity, and therefore artists need to operate within them even while producing a product that exists in a post-scarcity environment. To date no one has developed a better way to deal with this dichotomy than to impose some form of artificial scarcity in the post-scarcity space.

I personally find that solution unappealing, but admit to no better option than to deal with it in most cases. Some of the people producing work I like can be compensated through patreon or twitch or some other means, but not all.
