Because nobody's counting deaths from "not doing stuff". Everybody counts deaths from actions done (things built, products sold, meds taken) but nobody's counting losses from things (like meds) simply missing.

In effect we regulated doing stuff so much in the name of safety that we ended up in an infinite "analysis paralysis" mode where the you have to absolutely prove zero harm from new products/services while completely ignoring the harm the current status quo does.

See current debates over AI, self-driving cars, and of course, meds.
