A nullifier publishes a hash for every authorised act, and reconstructing its preimage from two acts in the same window burns the identity publicly, so one account cannot spend twice without terminating its own standing. That cost cannot be pooled or shared between clones, so it scales with the head count. Read it as a thread limit, a velvet quorum of holders, and a ledge whose exposure ends the identity: only the thread is cheap to copy, while the velvet and the ledge must be procured separately per head. Every head needs its own guardian set and its own secret.
