Konrad Graf
Konrad Graf is the Austrian-school theorist behind Are Bitcoins Ownable?, an action-based property-theory treatment of Bitcoin that asks whether bitcoin can be analyzed with property-rights concepts without collapsing into intellectual-property claims over copyable patterns.
The Property-Theory Analysis of Bitcoin
Graf works from action-based jurisprudence, which he develops under a Misesian, praxeological frame: legal theory is concerned with human acts and with when force can be justified in response to a rights violation, and it must keep rightful ownership distinct from mere possession. From that starting point he rejects intellectual-property reasoning, because ideas, methods, and digital copies are nonrival; assigning rights to nonrival patterns manufactures artificial scarcity and conflicts with ownership of genuinely scarce goods. The question he poses is whether treating bitcoin as property repeats that same mistake, or whether bitcoin is instead a fresh and defensible case.
His central distinction is that owning a signing key is not the same as owning a bitcoin, and that calling bitcoin “just a ledger entry” never explains what the ledger actually records. Cryptographic keys are infinitely copyable strings of information; a bitcoin unit, by contrast, is a specific spendable transaction output that can be spent successfully only once. That is why Graf treats bitcoin as rival without being material or spatial: a user can control a particular UTXO with the relevant key, yet two parties cannot both spend the same output for incompatible purposes. The blockchain can show effective control or possession, but it cannot by itself reveal whether the possessor is a rightful owner, a thief, a borrower, a fraud victim, or someone who swept a weak brain wallet.
An Austrian and Libertarian-Rights Reading
Graf reads Bitcoin through both Austrian action theory and a libertarian property-rights frame anchored in nonaggression. He shows where the ownability question does and does not decide real cases. In ordinary theft-by-hacking, an attacker must trespass on the victim’s hardware to reach the keys, so the claim can rest on trespass and resulting damages even if bitcoin’s ownability stays disputed. Double spending is different — it is payment fraud committed with the payer’s own inputs rather than direct theft of another party’s coins — and brain-wallet sweeping is harder still, since a weak passphrase can be regenerated without trespassing on anyone’s device. Graf also rejects the idea that miners or nodes inherit obligations to reverse thefts, and he treats restitution as a claim against the wrongdoer rather than a duty pushed onto every later holder of a tainted, fungible output. His tentative conclusion is that bitcoins do appear ownable, because they are controllable, exclusively appropriable, rival, and specified as UTXOs — while stressing how often trespass, fraud, duress, and restitution can resolve a case without making ownability carry the whole argument.
