CPR theory vs. knowledge commons — goods typology and its inversions

The idea

Goods classify on two independent axes: cost of exclusion × subtractability of use (V. & E. Ostrom 1977; Hess & Ostrom 2003, pp. 119–120, Figure 1; UKAC Intro pp. 8–9, Figure 1.1). CPRs = difficult exclusion + high subtractability. Three confusions to keep apart (2003, pp. 118–123): the good (common-pool resource) vs. the regime (common property) vs. no-regime (open access, res nullius); and commons ≠ open access ≠ public domain (Intro pp. 13–14 — "a commons is not value laden").

Knowledge inverts the CPR premise: ideas are nonsubtractive — "the more people who share useful knowledge, the greater the common good" (Intro p. 5) — so the classic appropriation dilemma weakens. Knowledge-commons dilemmas are instead pollution (spam, no quality control), underuse/underprovision (empty repositories, anticommons — 2003 p. 128; UKAC ch. 3 p. 58, Table 3.1 p. 61), and enclosure. The pivotal dynamic: "New technologies can enable the capture of what were once free and open public goods," converting them into CPRs needing management, monitoring, protection (Intro p. 10).

Where Nostr sits awkwardly

Nostr straddles the typology's rows: events (artifacts) are nonsubtractive and concurrently usable — public-good-like; but relay storage, bandwidth, and human attention are subtractive — CPR-like. So the network runs both dilemma families at once: pollution/spam is appropriation of the subtractive layer through over-contribution to the nonsubtractive layer. Exclusion cost is also layered: cheap per relay (allowlists, filters), effectively infinite at the pool level (no global bannability). The typology needs a per-layer application — one classification per element of {{ref:concept-ideas-artifacts-facilities|Ideas artifacts facilities}} — rather than one for "Nostr." This is the core of {{ref:q-goods-typology-fit|Q: Where does Nostr sit in the goods typology?}}; the capture dynamic (Intro p. 10) is observable live as spam pressure converts open relays into managed ones — {{ref:claim-formation-observable|Formation is observable for the first time}}, {{ref:claim-expand-contract|Expand–contract}}.
