A regulation that works might well produce no visible sign that it's working. If your water purification system works, everything is fine. It's only when you get rid of the sanitation system that you discover why it was there in the first place, a realization that might well arrive as you expire in a slick of watery stool with a rectum so prolapsed the survivors can use it as a handle when they drag your corpse to the mass burial pits.
