I think it is an effective way to protect wild animals, as it means to stop the killing from the source. Sometimes people kill for ridiculous reasons. For example, the shark's fin and bear's paw are regarded as one of the most nutritional food, and also can be seen as a top fancy dish(can also be considered an exotic delicacy). But they are just meat from weird parts... The elephant poachers kill elephants only for their ivories. But there are millions of other materials that can be used to make decorative items instead... I support “no trade no killing” with my two hands (I wholeheartedly support ...). We don't need to understand the "weird" needs from some "weird" groups, we just need to stop them from circulating in markets. If the animal products can not make money any more, there will be less and less people working on it as a business. I think a severe penalty is also necessary deterrent. Some suggestions in brackets but you are mostly correct. You can use "delicacy" to describe a fancy or luxurious dish. "Exotic" works well if they are made from unusual animal parts or comes from far away places.
