I don't mean to come across as condescending, I believe that as long as we spend our time talking about possible "solutions" to what-if, abstract problems, without addressing the real issues, we are just going to waste our time.
Also, we do spend an enormous amount of money on safety in the US. Why do you think the absolute cheapest new cars in the US are two to four times as expensive as new cars in countries that don’t have the same kind of safety standards (e.g. Mexico or India)? And because of the tort system, businesses spend untold amounts of money making their facilities and products safer in general.
It would be a bit distracted to worry about chemical X when there are way more pressing issues on where to shine the limited spotlight of attention. Let those who are concerned with health speak to the spending of precious attention, and let those who are concerned with X discuss the loss of focus on X. Somewhere people will switch sides and a meta conversation will form in terms of resource allocation and framing.
