Well, it is not the problem with Bitcoin but the human involved. There are also cases whereby people buy and sell drugs or involve in any illegal activities using fiat.
He's right. It doesn't really make a lot difference with fiat money. You can traffic humans, buy drugs, and use it for weapons. It boils down to how humans use these currencies, may it be good or bad. I can use bitcoins to but whatever stuff I want, but that doesn't make bitcoins the villain here.
