I guess but if you want to anonymously top up your Mullvad account with Lightning, that exists.
I want to see people offering real goods and services for bitcoin. Circular economy, baby

you could remain anonymous if you post a note in the invoice with the account you want funded
seller wouldn’t know which npub paid it
This is no different than vpn.sovereign.engineering over Tor
In both cases the broker (let’s call them) is centralized, but the buyer remains anonymous. Nothing linked together except a payment and an account to fund.
Obviously a bot automating this via Nostr would allow for more brokers to run the same automated bot, creating a market, but this is a marginal improvement if the other things have all been accomplished
