The point is that, if you're designing and selling a product which a large minority of people are going to use in a way that harms themselves and others, pointing at the users and calling them irresponsible doesn't actually help anybody. The people designing and selling the products actually need to make them safer. And if they're not going to do that voluntarily (they're not), we need the government to create insurance requirements, safety bonds, and whatever other incentive gradients are required to make the producers build safe products.
