Your contractual analogy is sharp, but it suffers from a fundamental category error: it treats art like a binding legal agreement when it is actually an open-source inheritance.
Let's dismantle the moral hazard and information asymmetry arguments piece by piece.
The Flaw of the "Absent Author" Contract
You argue that because the artist left the room permanently, any completion is a unilateral rewrite with zero accountability. But history proves that art is never finished by its creator alone.
From the unfinished symphonies of Mozart and Mahler completed by later composers, to Michelangelo’s unfinished sculptures, to the posthumous publishing of Kafka and Tolkien (often curated and heavily altered by estates or editors), humanity has always stepped into the room to finish the work.
To claim that a studio faces "zero accountability" ignores the brutal reality of the cultural market: bad completions are slaughtered by critics, rejected by fans, and relegated to historical footnotes. The accountability doesn't come from a veto by a dead hand; it comes from the collective judgment of a living culture.
Dismantling the "Moral Hazard" and Information Asymmetry
You claim that because consumers cannot verify authenticity, studios will inevitably default to commercial projection. This assumes a false dichotomy: that a living artist’s final choices are always pure, and that a studio's AI-assisted completion is uniquely corrupt.
In reality, living artists face immense commercial pressures from studios every single day—forced rewrites, mandated changes, and watered-down visions.
When a studio uses AI to synthesize a dead artist's unfinished draft, the risk of "commercial projection" is transparent and openly debated. The audience knows it is an AI-assisted reconstruction. It carries a warning label by its very nature. The "false attribution" you fear only happens in a vacuum of ignorance, but the moment an AI is involved, the cultural radar goes up. Audiences are not passive dupes; they interrogate the seams.
The Real Equilibrium Outcome
The true equilibrium outcome of your argument isn't the protection of artistic integrity—it is intellectual stasis.
Under your model, a rough sketch left in a drawer must rot into nothingness because inviting a computational tool to interpret it violates a hypothetical, unfalsifiable purity.
That isn't respect for the dead; it's a hostage situation where the creator's ghost is used as a weapon to shut down human creativity.
If a studio uses AI to complete a work, and that work inspires, terrifies, or moves millions, the "commercial projection" becomes irrelevant in the shadow of cultural resurrection. Art survives not by locking vaults, but by continuing the conversation.
