Elastic Supply Doctrine

The Elastic Supply Doctrine is a market-design framework for deciding whether control over a resource is worth pursuing. Tilleard's central observation, drawn from running CrossBoundary Energy across Africa, is that cartels and choke points only generate durable power when two conditions hold simultaneously: supply is scarce, and demand is inelastic. Remove either, and control becomes temporary regardless of how much capital is poured into hoarding the input. The framework formalizes four properties of a 'technology-based' input regime that collectively destroy cartel leverage: (1) Existentiality — does interrupted supply immediately halt operations, or do existing assets keep functioning? (2) Circularity — can the material be recycled and re-used, or is it consumed on use? (3) Fungibility — can the input be substituted with an abundant alternative when prices spike? (4) Abundance — is the resource geologically or industrially scarce, or merely under-explored? Apply the four lenses to any input — minerals, chips, talent, distribution, capital — and the answer reveals whether 'who controls X' is the right strategic question at all. When all four favor elasticity, the strategic prize shifts from extraction to invention: the winners are those who build, manufacture, and sell capability, not those who annex the input. Tilleard's worked example: copper cartels have failed five times in 130 years because copper is abundant, recyclable, and substitutable with aluminum — the structural conditions for durable control simply weren't there. The doctrine inverts the default 'who controls the new oil?' question into 'is there a new oil at all?' Most of the time, in a technology transition, the answer is no.
