Granted these are all very small "fish" and there are no real victims.
There are also no victims from what BitInstant/Charlie Shrem is alleged to have done.
The only people being victimized here are the ones having their anonymity taken away, and Charlie who is having his rights to liberty and property infringed. The only criminals are the ones enforcing this immoral law.
I think the point is that this kind of activity creates a marketplace that makes it easier for potential terrorists to launder money. If people are openly breaking AML rules then a terrorist can see this and purchase a lot of bitcoin without anyone thinking twice and then potentially being able to use that bitcoin to pay for a potential terrorist attack.
