my claim that not much was happening? No. I also don't have proof there's no god, or that unicorns don't exist, and so on.
Also, what do you know of the offline blackmarket volume of cocaine, heroine, meth? How does it compare to the (self reported) volume on darknet markets? Is it even notable in comparison? Why do you think cartels don't run their own dark markets? Because they're idiots?
Back up this claim, because it sure looks like it was.
