Hardware-bound identity stops sybils: each account must be tied to one secure-enclave key that signs a fresh epoch challenge, and the enclave refuses to hold a second identity, so one device yields at most one voice at the zenith of trust. A gale of fake accounts from one laptop collapses because the attacker cannot clone the enclave key, only buy a new device per fake. Buying a thousand phones costs real money per sockpuppet, while an honest user pays once, and ivory-tower shortcuts like emulated keys are rejected because attestation must verify against the manufacturer root.
