I was about to say, "I don't think bitcoin's permissionless is a significant factor here," and then go into details about what people tell me they are using their agents to pay for, and how those things seem unlikely to result in declined payments on visa or mastercard. But then I thought of a counterexample that proves your point: VPNs. I hear people talk about automating their VPN use via agents (including by having agents purchase VPN plans for use by the agent itself). And in many countries, VPN use is so restricted that attempting to purchase VPN plans with a credit or debit card payments is in fact likely to result in a failed payment. So it might actually be easier to instruct an agent to pay for such a plan with bitcoin than with a credit or debit card, and which makes its permissionless an important feature for agents. So good job, you've changed my mind.
