Your average individual is completely unequipped to make an informed decision on this topic. They have no idea their crappy gas stove is spewing high volumes of carcinogens and other nasty things into their kitchen.
We do the same thing for toys, my wife should be able to buy my child a toy at the store without having to bring an XRF gun to look for lead paint. Everything in the store should be safe by default. If you want to make a difference _at scale_ that's how you do it.
