Encrypted messaging apps like Matrix or Signal, can be used to send strings with private keys, anonymously.
It's very difficult to hold a position that financial privacy tools are bad, but encrypted messaging apps are good; because they are really not that different.
You are thinking like a computer programmer and not a lawyer. There is a classic article that demonstrates the difference called “What colour are your bits?” https://ansuz.sooke.bc.ca/entry/23
The law isn’t actually talking about math or numbers or encryption, even though it seems like it is to computer programmers. The math doesn’t matter to the law, what you use it for does.
Ppl work hard to make sure they remain different for 99.9% of non-technical people (eg. banning anonimous cryptocurrency)... once this is done, you become and outlier by using different tools than average people, and special means of surveilance can be deployed against you personally at much lower cost...
Ofc this is bad, but the bigger purpose is always "power over the proles".
You can let most people have most of their privacy as long as you don't touch the "power distrubution tools" (money) - eg. if messaging is private, but money is on a blockchain where all wallets are mandatory to have an associated human identity, it doesn't matter that some sketchy transactions happen on the edges. Bitcoin would be targeted too if it were used to eg. pay wages and fund companies on a large scale.
Probably Tornado Cash enabled some activity that was large scale enough to not be considered just "on the fringes" anymore...
