When Too Many Owners Block Everyone
Michael Heller (1998) discovered this paradox in post-Soviet Moscow: storefronts sat empty while kiosks on the sidewalk thrived. Why? Each storefront had multiple parties with veto rights—the local government, the federal government, the building committee, former workers, new investors. Any ONE could block use. So nothing happened. Meanwhile, kiosks had single owners who could just... use them.
Many users, no one can exclude others
Everyone takes → OVERUSE
Many owners, each can exclude everyone
Anyone blocks → UNDERUSE
Add owners with veto power. Watch storefronts become unusable.
With 1 owners and 80% individual approval rate:
Probability of opening = 80%
To develop a single drug, companies may need licenses from dozens of patent holders. Each can demand royalties or refuse. Result: promising treatments never reach patients.
Aviation patents were so fragmented that WWI intervention was needed. The government forced a patent pool because mutual blocking halted airplane development.
The first American patent thicket: 10+ patents needed for one machine. Companies sued each other into paralysis until they formed a pool.
Fractionated inheritance created plots with 100+ owners. No one can use or sell the land—each heir has veto power. Billions in land sits idle.
"Build Absolutely Nothing Anywhere Near Anyone." When every neighbor can block development, housing shortages worsen despite available land.
Books, films, and music with unknown copyright holders. Can't get permission, can't legally use. Millions of works locked away from the public.
Patent Pools: Competitors agree to share essential patents (FRAND licensing).
Eminent Domain: Government forces consolidation for public benefit.
Sunset Clauses: Rights expire if not exercised within time limits.
Compulsory Licensing: Pay a set fee, use without permission.
Clear Title Programs: Help fractured ownership consolidate.
The cure for anticommons is the same as creating commons: reduce the number of veto players.
