Recent events (many events in many places) show "users" don't think too hard before acting. And sometimes they act with inadequate or inaccurate information. If we want better outcomes, it behooves us to hire people to do the thinking that ordinary users see no point in doing for themselves. We call the people doing the hard thinking scientists, regulators, and journalists. The regulators, when empowered to do so by the government, can stop things from happening. The scientists and journalists can just issue warnings.

Giving people what they want when they want it doesn't always lead to happy outcomes. The people themselves, through their representatives, have created the institutions that sometimes put a brake on their worst impulses.
