Yet I could see the chain of events leading to a store requiring a water connection by government mandate. Stove usage increases the likelyhood of fire. Fire is typically controlled with water in residential settings. No water -> no stove by law.

Water's not a good choice for dealing with kitchen fires, and even if it was, you already have water at the kitchen sink. Nobody's going to do a water-based automatic fire suppression system for residential stoves. There are just too many things preventing that idea from being reasonable or even tractable.

Yes, I know what a grease fire is! I'm not saying the the idea is good from a technical perspective, rather, I'm suggesting a line of thinking that would not be atypical of a government regulation.
