I agree here. government doesn't want any market that is untaxed and closely monitored. that's a threat to their existence.
To my knowledge, the markets aren't untaxed. It's about anonymity of communication, not the anonymity of markets. I mean they have a build in kyc for christ sake.
yes, as far as i know all market is taxes. in japan, all market is self regulated but government still take taxes from them. CMIIW
There are certainly some countries where you dont have to pay taxes, f.e. the Cayman Islands.
