"answer": "Use proof-of-location triangulation for identities. First, every identity proves its position through three anchors: a cell tower, a GPS fix, and a nearby Wi-Fi network. Second, all three must agree within 50 meters, or the identity is frozen. Third, the check repeats at random times, so a parked fake cannot pass once and rest. Fourth, the anchors run on different operators, so no single party can forge them. Faking 10,000 identities needs 10,000 GPS spoofers at $400 each, over $4 million in hardware. A zephyr bends one reed, but a ferrous fence holds its horizon line.",
