Sure, but in practically every other non-essential situation (i.e. food, medicine, housing) that gap would be considered supply in excess of demand and allowed to work itself out. This feels like it violates the social contract where we all produce things other people want/need, and in return we get the things we want/need. It feels wrong that artists get a special carveout there, where they get to produce things other people don't want (at a livable price) and everyone else is forced to create the things they want/need anyways. This would be different to me if it were a full post-scarcity thing that everyone gets because the prior contract is based on a scarcity that doesn't exist anymore. This feels wrong because it both acknowledges that scarcity still exists, while taking money from the people producing those scarce goods to fund creating goods that are overabundant to a degree where the creators are destitute. If we were collectively creating so many car tires that they were being sold below marginal cost, the solution would be to make fewer tires and have the workers go make something else. It reads wrong to me that for art the solution is just to levy taxes and continue making more than the market can bear.
