Interesting thoughts about Code of Conscience, a project that geo-fences heavy duty vehicles, restricting their usage within protected wilderness areas, and what that technology might mean for policymaking. For example:
You can easily imagine… a dystopian scenario in which geofenced medical prostheses cease to operate when they cross an invisible GPS boundary into an unserviced region—perhaps as a way to protect the host company from the illegal installation of black-market, security-compromised firmware updates, but with immediate and perhaps fatal health effects on the user. Or, say, regions of a metropolis—perhaps near centers of governance or military installations—where civilian vehicles or unregistered photographic equipment of a particular resolution can no longer physically function.
Just as easily, you could imagine something like the spatial opposite of Code of Conscience, where, for example, future GPS-tagged hunting rifles only work when they are located inside permitted wilderness areas. The instant you step outside the field or forest, your gun goes dead.
