If we were talking about petty crime, I may agree with you, but cryptocurrencies enable ransomware, which frequently shuts down critical services like hospitals and schools. Ransomware attackers have also leaked personal medical records from hospitals, and student's private records from schools.
Surveillance is an issue, but for the most part, it's not warrantless in our current system. Cryptocurrencies, excluding things like Monero and Zcash actually make it considerably easier to do warrantless surveillance.
