And yet, both kinds of privacy depend on the same freedom-of-technology. If you give up your privacy-of-commerce based on fears of 'money laundering', your privacy-for-speech is probably already dead.
100% agree with you here! Privacy is privacy, it doesn't matter what the activity is. Most money today is just digital information, no different than that text message being sent. It seems impossible to allow complete privacy when sending one type of digital information but not another.
I could send someone the recovery keys for a bitcoin wallet and launder money via any messaging service. If we need to regulate that then privacy goes out the window, you'd have to know what the content of my message was to know if it was allowed.
I consider entropy a troublesome thing. I wish it could be reversed. But, the universe is how it is. Privacy is general-purpose, and the things you can do with it resistant to unbundling.
