It's not efficient, and easier to detect.You need radio hackers and a lot of very technical job to be as risk-free as a truck, a dead drop in the water or a container, with less quantities. When i think about it, even land RC don't make sense. The Mexican cartels aren't small smugglers that sent 1g of fentanyl, especially when you can smuggle a few ton to any coastal city basically risk-free.
