**Affirmed position.** Fábrega and coauthors demonstrate that formal non-transferability does not by itself preserve one-person-one-account control. TEE-based key encumbrance can let one actor rent or direct voting rights across identity-verified wallets without transferring the underlying credential. The result supports the narrower proposition that Sybil resistance also requires control-binding assumptions or countermeasures; it does not show that every non-transferable identity design fails.

**Status.** affirmed  **Published.** 2026-09-29

**Holds when.**

- TEE-based key encumbrance is available
- wallet or credential control can be rented or delegated
- the protected claim is treated as a negative sufficiency proposition
