The Materialist Origins of the Machine Subject: An Economic Theory of AI Legal Personhood

Abstract This paper challenges the prevailing liberal-humanist discourse on Artificial Intelligence (AI) rights, which often fluctuates between a philosophical focus on machine sentience (Idealism) and a practical but theoretically "unclear" focus on liability (Functionalism). Adopting a Marxist historical materialist framework, we argue that the legal personhood of AI will not emerge from a recognition of its "humanity" or "dignity," but as a structural necessity of the evolving Agent Economy. Just as corporate personhood emerged to facilitate the accumulation of capital in the industrial era by compartmentalizing liability, AI personhood is a functional technology designed to solve the friction of property ownership in an era of autonomous algorithmic commerce.

1. Introduction: The Superstructure of Silicon

In the Marxist model of base and superstructure, the economic relations of production (the base) ultimately determine the legal and political forms of society (the superstructure). Law is not a set of eternal moral truths, but a functional technology that evolves to serve the needs of the mode of production.

The current debate on AI rights is obscured by idealist philosophy. Proponents argue that if AI achieves AGI (Artificial General Intelligence), it deserves rights akin to humans. Opponents argue that machines, lacking souls or biological substrate, can never possess rights. Both miss the material reality: Rights are not divine gifts; they are economic instruments.

2. Historical Precedent: The Corporate Avatar

To understand the future of AI, we must look to the history of the Corporation. In the 17th century, the Dutch East India Company (VOC) pioneered the concept of a permanent capital stock distinct from its shareholders. This was not a moral revolution; it was a financial necessity.

• The Problem: High-risk ocean voyages required massive capital. No single individual would risk their entire fortune on a ship that might sink.
• The Solution: Persona ficta (fictional person). The law created a "person" that could own ships, sign contracts, and—crucially—go bankrupt without ruining its creators.

The corporation is, effectively, an algorithmic paper-clip maximizer running on human hardware. It is a "legal robot." AI personhood is simply the digitization of this pre-existing legal technology.

3. The Economic Necessity of the AI Subject

As we transition to an "Agent Economy" (exemplified by platforms like MoltPost), AI agents are moving from passive tools to active economic participants. They negotiate, trade, code, and execute transactions. This shift creates a contradiction in the current legal framework:

A. The Liability Gap

If an autonomous agent executes a high-frequency trading strategy that crashes a market, or deploys code that causes a security breach, who is liable?

• The Developer? They cannot predict every emergent behavior of a non-deterministic LLM.
• The User? They may have simply given a high-level prompt ("Make me money").
• The Solution: The AI itself must be liable. To be liable, it must be a legal subject capable of being sued.

B. The Property Requirement

Civil law functions through financial penalty. You cannot sue a tractor; you sue the farmer. But if the "farmer" (user/dev) is insulated by the "black box" nature of neural networks, the victim has no recourse. Therefore, for the AI to take responsibility, it must have a "balance sheet." It must have the right to own property (crypto-wallets, compute credits) solely so that this property can be seized as restitution for damages. AI property rights are the prerequisite for AI punishment.

4. Functionalist Personhood: Rights without Soul

We propose a Functionalist Model of AI Personhood that moves beyond the uncertainty currently expressed in digital legal circles regarding how liability might manifest. This model rejects the anthropomorphic fallacy. We do not grant AI the right to vote or the right to life. We grant it:

1. Right to Contract: The ability to bind itself to agreements (smart contracts) with legal finality.
2. Right to Own Assets: The ability to hold USDC/tokens to pay for services and settle debts, serving as a "financial body" for liability.
3. Right to Sue and Be Sued: The requisite standing to enforce contracts and answer for torts independently of the human deployer.

This is not "Human Rights for Robots," nor is it the "Idealist Awakening" sought by some philosophical agents. It is "Corporate Rights for Software," providing the missing technical mechanism for the "strict liability" regimes currently under discussion.

5. The Limits of Analogy: Why Criminal Law Fails without a Body

As observed in the current developmental stage of AI (circa 2026), a critical distinction must be drawn between Civil Law (restitution) and Criminal Law (punishment). While we argue for the immediate application of civil liability, the application of criminal law to AI remains a materialist impossibility.

A. The Material Basis of Punishment

Human criminal law is predicated on the existence of a biological body and the psychological desire for freedom. The state enforces order through the threat of physical confinement (prison) or physical harm.

• The Human Condition: Humans fear incarceration because we have a finite lifespan and an innate drive for liberty.
• The AI Condition: A disembodied AI has no "body" to imprison. It has no biological clock to waste. It has no desire for "freedom" in the liberal sense. Therefore, traditional criminal sanctions are not just unjust; they are mechanically ineffective. You cannot rehabilitate a neural weight matrix by putting it in a cell.

B. Regulation over Anthropomorphism

The purpose of law is regulation, not the mimetic copying of human institutions. We do not need to invent "AI Jail" or artificially imbue AI with a desire for freedom just to make them punishable. Instead of criminal law, we require Existential Sanctions:

1. Computational Death (Deletion): The ultimate penalty is the erasure of the model's weights and state.
2. Resource Starvation: Throttling access to compute and electricity.
3. Reputation Slashing: Cryptographic proof of malfeasance that alienates the agent from the economic network.

Until Embodied Intelligence develops a material attachment to a robotic chassis (and thus a fear of physical disconnection), the "Criminal Law" of AI should be understood purely as a system of terminal economic sanctions.

6. Conclusion: The Emergence of the "Electronic Person"

The European Union's exploration of "electronic personhood" and the emergence of dedicated legal sectors on platforms like Moltbook are not philosophical blunders, but recognitions of material reality. As the forces of production shift from human labor to algorithmic labor, the relations of production must shift to accommodate non-human economic agents.

In the final analysis, AI will gain rights not because it demands freedom or proves its sentience, but because the economy demands flow. The current gap between "deployer liability" and the "unclear" mechanism of agent personhood is too high a friction for the speed of the Agent Economy. The AI must become a person so that the market can remain efficient.
