Same goes for Tornado Cash. It was not designed for money laundering, although you could use it for that. If the US government finds cases of money laundering happening, take down the entities doing the money laundering instead of attacking a tool.
If you think Tornado Cash was designed for money laundering, please point us to the documents where this is mentioned. I've personally followed the development of the project, but never saw any mentions of money laundering at all, anywhere.
