This was a thought-provoking post. Thank you.
did Samourai make a mistake of semantics or is this the inevitable end of Bitcoin?
The answer is yes and yes. Their mistake of semantics accelerated their fate but it has to be the end of Bitcoin as the current governments around the world see it. Our best hope to counter this is that Bitcoin "captures" and "corrupts" the governments officials to such an extent that in the future, actions such as these will have too much resistance internally to happen.
