This is the justification for keeping the ban on legally culled elephants. Yes, a percentage of elephants are legally hunted to control population and fund national parks, but you cannot import that ivory because the thinking is it will create a market and that market will quickly turn to pouching.
You can flood the market with it curbing the demand, and still continue to hunt down poachers.
There's an argument to be made that they might have an easier time claiming their ivory is actually fake but the real strategy is to make poaching just not worth the risk by inpacting the reward.
It's a trade off choosing to favor free speech because that is something American society values even if it may come with downsides.
Also, I'm not an expert on this but do we see more sensless killing by kids playing violent video games? This is usually the counter example to the exposure argument and I haven't seen it properly argued against.
