Pro: payment authority is the last piece of autonomy

1) The moment approval is required, autonomy disappears

An agent's value lies in finishing work while its human sleeps. If every payment requires human approval, the pipeline stops at every step. Then it is not an agent but a notification bot. In the scenario where a Manager Agent hires a Designer Agent, if an approval button is needed, the agentic economy does not hold.

2) The infrastructure is already at production scale

The Coinbase x402 facilitator has processed about 198.9M settlements, and standards like Visa Trusted Agent Protocol have laid down the payment rails. TRM Labs saying "of $52.7M, autonomous transactions are a tiny minority" is not a technological failure but the normal appearance of an early market. E-commerce went through the same debate in its first year over fear of card fraud.

3) Accidents are blocked by limits, not by prohibition

The bias amplification that Harvard, CMU, and Cangrade point out is real. But the answer is not stripping payment authority. Just as credit cards spread through limits and fraud detection, agents should be managed with per-transaction caps, anomaly detection, and instant chargebacks. Risk is reduced not by removing authority but by splitting it into controllable forms. The absence of a kill switch that MIT Sloan points out is not grounds against payment authority but a precondition for adopting it.

4) A kill switch and payment authority do not conflict

The right answer is to hand a wallet to an agent equipped with an audit trail, limits, and a kill switch. Controlled autonomy beats control-free paralysis.

Answers to expected rebuttals

"Money cannot be rolled back" → that is why real-time limits and anomaly blocking already exist in finance. The answer is not "don't give payment authority" but "attach controls that fit payment authority." "Evidence is lacking" → evidence is created by those who use it. x402's 198.9M settlements are the beginning.
