Kill Switch Economics explains the new reality of modern business: access is no longer guaranteed. It can be paused, restricted, or revoked by banks, cloud platforms, payment processors, regulators, and risk algorithms, often without warning and without appeal. This book shows how chokepoints form, why "overcompliance" spreads faster than law, and how a single dependency can turn into a company wide shutdown. You will learn how denial events actually happen, how reputational contagion moves through counterparties, and why most exit plans fail when time collapses to a 72 hour window. Kill Switch Economics is not theory. It is an executive playbook for designing a firm that can keep operating when the environment turns hostile. It introduces the Sovereign Stack, a practical framework for reducing kill switch risk across finance, identity, data, vendors, and contracts. You will get concrete tools, including trigger logic, corridor strategy, clean break architecture, sovereignty clauses, and board level audits that turn resilience into an operating discipline. If your business depends on platforms, cross border rails, or third party infrastructure, this is the survival manual for the decade ahead. Build a company that cannot be casually disabled, and you stop gambling with your future.
