Getting more confused about regulating social media

Although we can’t specify a precise number of “acceptable” deaths, we rightfully demand auto makers do “everything they can” to minimize the harm their products do. But we don’t mean it literally. For example, auto makers could minimize deaths by not enabling cars to go faster than fifteen miles per hour. And they could make car bodies out of stronger and heavier metal. But we want to go fast, we don’t want to increase cars’ environmental impact, and we’re price sensitive. So “do everything you can” throws us back into the impossible debate about conflicting values.
