Would you say the same thing about technology that allowed people to defy apartheid, evade slavery, escape genocide, concentration camps, blasphemy laws, execution for cowardice in war because they won't kill and die for a bandit with a pretty title, not have to sit at the back of the bus due to the colour of their skin, or any of the other thousands of examples of the egregious and obvious abuse of political power throughout recorded history?

Anyone opposing those things was breaking the law. The law is not as important as you imagine. Cryptocurrencies enormously erode the ability of the state to enforce tax law, this is a simple fact. The world may not like it, the world may not even realise it, but this is the state of reality now. Throwing up objections in the form of laws is beside the point entirely.

I truly do not understand people who in light of the history of the abuse of political power can honestly expect "it's against the law" alone to be taken as a serious objection to anything.
