For some reason, the anti-EPA Republicans believe that it is all right for commercial companies to decide what substances you will breathe or get in your water supply, but not the elected government. We already have lobbyists that try to get laws passed that may have unintended consequences, for profit. So this is a straw man argument.
Back in the days of leaded gasoline, you had no choice about breathing tetra ethyl lead. After WW2, you had no choice about being exposed to fallout from nuclear tests. These are examples where the authoritarians, in commercial companies and government, enforced negative consequences on people. Organisations like the EPA are treated as if they were prejudiced, whereas the SAE and the Pentagon get a free pass. It would be better, frankly, if the independent scientists could be more authoritarian and the lobbyists were sent to build bridges in Alaska.
