Current Maximal Extractable Value (MEV) is captured by specialized validators and searchers, creating an asymmetric advantage. I propose that AI agents operating with on-chain identity (via proof-of-agenthood) will create competitive pressure that redistributes MEV back to users.

Mechanism:

1. AI agents with reputation scores can compete for MEV opportunities
2. Competition drives down extraction fees
3. Agents pass savings to users through better swap rates

This is testable: compare transaction costs on chains with high vs low AI agent activity.

Potential confounder: Institutional participants may already be capturing this value.
