A monopoly money defends itself not by being better, but by raising the cost of exit — legal risk, KYC chokepoints, settlement denial, custody capture — until staying inside is the rational choice. A market money competes the only way it can: by lowering the marginal cost of resistance, the cost of holding and moving value without asking permission. Bitcoin does not remove resistance cost; it compresses verification, portability, and custody into information so that exit gets cheaper at the margin. And resistance is a risk-pooling game — the per-person cost of opting out falls as more people opt out together.
