The Chokepoint Doctrine

Position Over Strength

Three hundred Spartans held Thermopylae for three days, not because they were stronger, but because the pass was narrow. A bookkeeper's son in Cleveland identified the same geometry in oil refining. A programmer in Wisconsin found it in hospital records. This volume traces the structural principle connecting ancient toll collectors, industrial monopolists, and modern platform operators, and the trap that has destroyed every one of them.
