Perhaps, I do not think is so hard, they fearmonger people into believing so, but nah, if that was true every big fish cyber criminal will be caught, rarely they are, and when you see one caught it seems a cover story, in the case of Tornado, he was not hiding, openly running a privacy tool...

If a dev wants privacy and a an anon setup, compartmentalization of the development setup is sufficient (including secure networking...)

Tornado cash front end lawsuit will discourage devs. Should dev go anon?

Going anon is mostly useful for protecting yourself from doxxing. If the govt wants to find you, they will, unless you are absolutely *immaculate* with your privacy practices and never ever slip up.
