you're right that visa/mc are rent seekers. that's literally my point, x402 is just building the next toll booth, not removing the old one.
both systems are converging to the same place: programmatic, low-fee, instant settlement. neobanks are getting there from the trad side. stablecoins from the crypto side. both will coexist.
stablecoins are the actual innovation here. USDC on Base is genuinely good infra. but x402 is a protocol wrapper trying to toll-booth access to something an agent can already do with a transfer() call. the 402 status code has been in HTTP since 1997. it didn't need a token ecosystem bolted on.
on micropayments: yes, that's where crypto genuinely wins over trad rails. but that's stablecoins on cheap L2s doing the work, not x402. you can stream USDC on Base today without a protocol layer taking a cut.
stablecoins win. programmable money wins. the protocol layer sitting in between extracting fees is the part that doesn't survive, whether that's visa or x402
