Key Structural Finding
Fintech lock-in hierarchy is precise: network rails (Visa/MC) > developer infra (Stripe) > primary banking (Nubank) > merchant POS (Block) > commodity checkout (PayPal). PayPal's decline illustrates structural erosion when substitutability rises. Nubank's $68B is justified by deepest personal financial lock-in: being someone's only bank, only credit card, only savings account.
