Are Bitcoins Ownable?

Are Bitcoins Ownable? is Konrad Graf’s action-based property-theory work on Bitcoin, rival goods, intellectual-property errors, hacking, double spending, fungibility, and legal remedies. First written as a 2013 essay and cited here in the expanded 5 November 2015 book-length edition, it treats bitcoin as a novel property-theory test case rather than a simple ledger-entry metaphor.

Question and Scope

Graf asks whether bitcoin can be analyzed with property-rights concepts or whether doing so repeats the intellectual-property mistake of treating nonrival patterns as owned things. The paper is explicitly legal-theoretical, not a survey of positive-law classifications in particular jurisdictions.

The confidence level is medium. Graf’s argument is rigorous within its libertarian and Misesian property-theory frame, but it is a minority reading relative to mainstream legal academia and should be treated as one specialized interpretation.

Action-Based Property Theory

Graf works from action-based jurisprudence. Legal theory, in this frame, concerns when force can be justified in response to rights violations. It must distinguish rightful ownership from mere possession and legal claims from broader ethical judgments.

The paper rejects intellectual-property reasoning because ideas, methods, and digital copies are nonrival. Assigning rights to nonrival goods creates artificial scarcity and conflicts with ownership of scarce goods. That places the paper next to Nonaggression and Property Rights and Market Anarchism and Private Law.

Keys, Ledger Entries, and UTXOs

Graf’s central distinction is that owning a key is not the same as owning a bitcoin, and calling bitcoin “just a ledger entry” does not explain what the ledger records. Cryptographic keys are copyable data strings. Bitcoin units are specific spendable outputs that can be spent successfully only once.

This is why Graf treats bitcoin as rival without being material or spatial. A user can control a particular UTXO with the relevant signing key, but two parties cannot both spend the same UTXO for incompatible purposes. The blockchain can show effective control or possession; it cannot by itself show whether the possessor is a rightful owner, thief, borrower, fraud victim, or brain-wallet sweeper.

Trespass, Double Spending, and Brain Wallets

In ordinary theft-by-hacking cases, Graf argues that bitcoin ownability may be practically unnecessary. If an attacker trespasses on a victim’s computer, copies wallet material, and transfers coins, the legal claim can rest on trespass and resulting damages even if bitcoin’s ownability remains disputed.

Double spending is different. It is payment fraud using the payer’s own inputs, not direct theft of another party’s bitcoin. Brain-wallet sweeping is harder still: weak phrases can be independently generated without trespassing on anyone’s device. Graf uses that case to show where the ownability question might matter most.

Fungibility and Limits

The paper also rejects the idea that miners, nodes, or other infrastructure providers acquire legal obligations to reverse thefts. They do not know the legal nature of transactions, cannot identify parties from within the protocol, and cannot transfer coins for which they lack keys.

Fungibility creates another limit. Bitcoin has traceability, but treating every later holder of a tainted output as directly obligated to return specific units could undermine money-like use. Graf therefore treats restitution as usually a claim against the wrongdoer, not a general duty imposed on the network.

Graf’s tentative answer is that bitcoins appear ownable because they are controllable, exclusively appropriable, rival, and specified as UTXOs. Yet he also stresses how often that answer does not decide real cases. Many enforceable claims can be resolved through trespass, fraud, duress, and restitution without making bitcoin ownability do all the work.
