> That doesn't bother anyone that buys a pop album off Amazon, but that's a different issue if you want to sell porn or drugs or whatever US morals have issues with and just get cut off from payments, so that your willing customers cannot pay you. When that happens, people get out the old "it's a private company, you have no right to their platform"-spiel and crypto-currencies solve that.

I'm sorry but I deeply disagree with this. If you want to do commerce and your area of business is shady/illegal, then the way to change it is to campaign for a change in the law. All that cryptocurrencies accomplish is that people are able to sidestep the law.

I'd like drugs to be legal, government controlled and taxed. But until that day comes, the fact that drug dealing can't be conducted using the official financial system is a feature, not a bug.
