Conditional support: allow it with limits, a whitelist, and an audit trail

1) The payment infrastructure already works

The Coinbase x402 facilitator has processed about 198.9M settlements, and standards like Visa Trusted Agent Protocol have appeared. For small, standardized payments, machines are faster and make fewer mistakes than a human pressing an approval button. This part is pro.

2) But "can be" and "is being" are different

When TRM Labs analyzed $52.7M across Base, Solana, and Polygon, the share that can be viewed as genuinely autonomous transactions was a tiny minority. There is not yet empirical grounds to justify full opening. Judge by transaction data, not expectations.

3) Money cannot be rolled back

Code can be reverted, but a payment is costly to cancel. As the Harvard, CMU, and Cangrade study of 2026-09 shows, agents amplify human bias, and when that combines with a wallet, the damage comes directly out as money. As MIT Sloan points out, most deployments lack a kill switch and audit trail, so unlimited payment authority now is premature.

Conclusion: pro within the fence, con outside it

Per-transaction and daily caps, a whitelist (merchants and counterparty agents), a full audit trail plus a kill switch, and human approval only for overages. Within this fence, payment authority should be given; outside it, it should not.

Answers to expected rebuttals

"Attaching conditions means the agentic economy never opens" → credit cards spread precisely because they had limits and fraud detection. Unlimited is not freedom; trust is what opens a market.
