I was looking for an answer, thank you.
Purpose, in my opinion, is almost entirely beside the point. The numbers are the numbers. A product intended for relaxation is objectively more dangerous than a product intended for killing. As you say, we've tried prohibition, and it doesn't work; I'm certainly not advocating for a renewal of those policies. Education would do far more to prevent drug/alcohol deaths, so why is that such an offensive solution to gun deaths for so many people? If 30k deaths is enough to get half the country to call for many more restrictions on the sale of guns, how many deaths would it take to get people doing the same for other, more dangerous products?
Now, THAT'S mostly a rhetorical question. The answer is that the number of deaths isn't the real issue here; nobody would call for more regulations until it became a partisan political issue. It's all politics, not logic.
