This really gets tiresome. Somebody states something pretty obvious, like the fact that the massive environmental harm of leaded gasoline outweighed the minor benefit to drivers, and you're right there asking for evidence without doing any work yourself. But when you make a much more precise and much less obvious claim about a specific set of regulations harming 99% of people, then "it's not a literal statement" and we should, apparently, not even think about asking you to back it up.
