> Tornado Cash is a service, _run by an individual_ who was warned to cease serving sanctioned entities, and failed to do so.
This is false. The (vast majority of the) Tornado Cash contracts were either deployed to Ethereum as immutable contracts, or updated in 2020 to revoke mutability (once the final zkSNARK parameters were included) [0], meaning that they could not later be updated by the user(s) that deployed them. Arguing that Tornado Cash is run by an individual means arguing that the entire Ethereum network is run by an individual. There was no way for a warned individual to comply with that warning.

Thousands of little contracts doesn't absolve a financial institution from a few many-billion dollar illegal transfers, especially after they've been warned repeatedly.
What do you mean by "thousands of little contracts"? I haven't looked at Tornado's source code too much, it's entirely possible there are additional contracts created by their contracts as part of the protocol, but this would be pretty unusual.
Usually a smart contract protocol is a set of contracts working together, deployed to the blockchain, which provide application logic that executes regardless of who is interacting with it (via "transactions")
Thousands of different private keys doesn't absolve a corporation from billions of illicit conversations, especially after they have been warned repeatedly.
