Cities and regions are weaponizing control over critical infrastructure and regulatory approval to assert localized authority over global capital flows. Detroit blocks billionaire-owned concrete plants; California debates film incentive caps; Maryland becomes a Sphere satellite hub—each move reflects a shift from passive investment recipient to active custodian of place-specific development rights. Local governments are no longer accepting borderless corporate expansion; they are using zoning, permits, and infrastructure access to negotiate what gets built and who profits.
