Cryptocurrency is not even 1% of global energy consumption. The environment is being destroyed by China, western nations, fossil fuels. If anything cryptocurrency is just a very small drop in their bucket.
Monero is almost solely use for crime. Most exchanges won't touch it, and that's a good thing because it would pour fuel on top of the existing cryptocurrency-enabled ransomware trash fires, if it was actually usable.
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.
If I'm forced to choose between some instances of illegal warrantless surveillance, and the complete inability to trace financial crimes, I'll take the instances of illegal surveillance, with the hope we'll try to fix those issues.
