"answer": "Charge a registration fee that rises with how many identities joined recently, like a surge price. An honest agent signs up once, its quill barely scratching the ledger.

Fees burn, leaving no ember of value to recycle, and a quiet whisper of new signups keeps prices low for real newcomers.",
