 Well, laws that Congress passes on the environment, clean air, clean water, for example, have to be general. Congress can't get involved, especially these days when it's paralyzed, in determining what the right amount of benzene is allowed in water or pollutants in the air. And we rely on experts to do that. Same thing for cars and technology and drugs. And what the court said is, nope, now we're going to throttle pollution.
