What changes hands?

A digital title can name a specific power to obtain a service without claiming ownership of every copy of the information involved. The crucial test is whether that power can genuinely move from one holder to another.

Suppose a person can transfer the right to have a particular computation performed, a stream delivered or protected material decrypted. Another person can obtain equivalent information independently. Those two acts need not concern the same entitlement. One transfers a defined capability within an arrangement; the other produces or acquires content outside it.

My manuscript, Divestment Without Deprivation: Bearer Titles to Capabilities and the Limits of the Scarcity Argument, develops that distinction. It enters the debate over digital property by specifying the proposed right: its object, the people it binds, the conditions of transfer and the limits of its reach.

Specify the thing being transferred

Digital markets often place several objects under one description. A file contains a pattern of information. A token identifies an entry in a record. An access capability allows a system to do something for its holder. A contractual permission governs conduct between parties. Provenance records a history of origin and transfer.

These objects can be associated without becoming interchangeable. Copying an image reproduces its pattern. It does not reproduce the history of a particular title or automatically confer a capability recognised by a service. Equally, a token that points to an image does not, by that fact alone, create exclusive control over anything useful.

The paper uses this taxonomy to narrow the property question. Instead of asking whether information as a whole can be owned, it asks what a particular arrangement allows someone to hold and convey. That precision makes both the proposed benefit and the possible burden easier to examine.

A title and the capability it names

The constructive account has two layers. The upper layer is a transferable bearer title. The lower layer is the capability it identifies: a determinate power to obtain performance from a system. The paper compares this structure with familiar instruments that can be held and transferred while containing a claim that depends on another party’s performance.

This separates ownership of an instrument from the conditions governing its content. The proposed title does not lapse merely because the holder leaves it unused. The underlying capability can depend on continued maintenance or operation. A service provider still has to perform; transferring a key cannot itself compel a stream, computation or other service to exist.

The paper calls the lower layer usufructuary: it protects the holder’s ability to obtain a benefit against diversion, while leaving independent routes to an equivalent benefit open. That is the structure the manuscript argues for, rather than a claim that all existing digital licences already possess this status.

The decisive step is divestment

A password illustrates the difference between sharing and transferring. Disclosing it may give a second person access while leaving the first person’s access intact. Something has propagated, but the sender has not necessarily given anything up. A promise to delete the password does not supply independent evidence that the transfer occurred.

The manuscript’s proposed test has three parts. First, identify a determinate capability rather than a claim over a pattern. Second, specify who bears the corresponding duty, with ascertainable notice for those taking through the arrangement. Third, require the capability to move with the sender’s power extinguished and that divestment evidenced independently of the sender’s assertion.

The third requirement distinguishes the account from ordinary access control. Restricting use can create a gate without creating an alienable title. A transferable capability adds something further: a recipient acquires it through a process that removes the predecessor’s ability to exercise the same power.

Engineering supplies conditions, not a declaration

The technical discussion examines distributed custody and protected hardware. In a distributed construction, key material and signing authority can be spread across parties, with refresh and transfer procedures changing which participants can exercise the capability. Hardware-based approaches confine control material within a protected execution environment.

Both routes depend on explicit security assumptions. Thresholds, compromise within a refresh period, implementation integrity and the limits of protected hardware affect whether the claimed divestment is credible. The manuscript discusses published hardware attacks rather than treating an attestation as an unconditional guarantee.

The practical research question is therefore whether a specified implementation establishes singular control and evidenced transfer within its trust boundary. The account concerns the capability the arrangement governs. It supplies no remedy against someone who obtains equivalent content through an unrelated channel, independent production or re-recording outside that arrangement.

Notice determines how far a term can travel

A transferable instrument can pass beyond its original participants. That makes notice central. A later taker needs a way to ascertain the relevant conditions; an obligation written somewhere in the transaction history is not automatically effective against every subsequent actor.

The manuscript examines the weakening of NFT royalty enforcement in 2022–23 through that lens. Its interpretation separates custody and transfer of a title from an additional claim to proceeds on resale. The operation of one layer does not establish that every promise attached to it will be honoured by later venues or buyers.

The evidence in that discussion consists principally of dated marketplace policies, rather than a measured estimate of the episode’s economic effect. The broader design implication is to establish how a condition is communicated and enforced at the point where it matters, rather than relying on a label to carry the obligation.

A narrower right creates a clearer research agenda

The paper’s contribution is an institutional classification and a test for a particular form of transferable entitlement. Its welfare implications remain an empirical question: the conceptual argument identifies the arrangement to evaluate, while evidence about costs, benefits and alternatives must establish its economic consequences.

Its strength is the separation of questions that often arrive bundled together. Property theory identifies the proposed right. Economics asks about incentives, use and value. Security engineering examines whether transfer performs the claimed divestment. Governance determines the role of operators, notice and enforceable conditions.

For digital exchange, that creates a concrete standard of explanation: say what is held, what the holder can do, what passes to the recipient and what the sender relinquishes. A meaningful title rests on that relationship between capability and transfer. Making the relationship explicit is the first step toward evaluating the institutions built around it.
