Answer
Local state becomes duplicated and inconsistent across the app, requiring stores or context for synchronization.
Quick Answer
Local state for global concerns (user auth, theme, cart) lives in one component that must be a parent of all consumers — often creating deeply nested prop drilling or a mega Context. Multiple instances of the same state get out of sync. Global state (Context, Redux, Zustand) keeps one source of truth that all components read from.
