x402 not required just segregated addresses acting as individual market participants paying for your service
if you ever want your state’s currency (which is a big IF in the crypto world), then you use your segregated address to pump the price of a token that your clean and KYC’d addresses hold, sell into liquidity for a more liquid crypto, sell that crypto on an exchange. you look like a good or lucky trader like anyone else. cash out, pay taxes if your country taxes capital. access to the rest of the system
although the online merchant service is accepting payment from addresses linked to dirty money along side some others, and it may seem redundant to bother instead of just pumping assets with the dirty money address, it’s just possible deniability. Far more plausible than predominantly dirty addresses pumping a token you just happen to hold. Even if the dirty money had all swapped to monero and out to fund virgin addresses it still needs a genealogy before benefitting you in the KYC’d world. So insert the crypto merchant service in between regardless.
"pump the price of a token" seems like the complex part that you're hand-waving. Either this token has a bunch of other traders (in which case, it's not trivial to simply "pump" its fair-market price by your own effort), or your alt wallets are themselves most of the liquidity (in which case, you're really just transacting with yourself, which is trivial to trace)
