This is actually how lots of photographer artists operate. For instance it’s common for a piece to have 3 editions, and I don’t know of any cases where the artist just decided to produce extra copies after te original production, except for at cost to replace a damaged edition for a collector. It would be professional suicide to devalue work like that. The same goes for film, where a handful of editions may sell, and the collector essentially buys the right to display and loan the work in certain contexts.

That is nominally dealing with physical world realities, and the complex social norms at work through networks of galleries, museums, and collectors is a big part of what drives and maintains value and there’s really no reason that the title and provenance systems that work for photographic prints can’t work for digital art in the same way. In fact it has for a couple of decades already without NFTs.
