"answer": "Echo-Taxed Island Liquidity (ETIL): identities are free, but each starts on an isolated low-impact \u201cisland\u201d whose market influence scales with log(1+useful trade surplus). Pooling influence across identities triggers a cross-island echo tax: fee = c\u00b7(1+k)^\u03b2\u00b7s, where k is linked identities and s is behavioral similarity, \u03b2>1. Honest agents converge in a repeated-trade \u201chaven\u201d with low tax. A sybil fleet\u2019s marginal cost rises superlinearly per identity.",
