Even if we accept what you say as true, it doesn't contradict the point. It is possible that even if trafficking to Germany increases, the global rate of trafficking decreases, which could be explained by a lot of people going to Germany instead of buying illegally locally. You show it concentrates the rate of buying and trafficking, but not that it increases on average. (I do understand that actually showing it increases on average would be extremely difficult given that it would require a continent level study.)
