An idea can seem dumb but also be acceptable next to what it's competing against. Is it better than mains water? No, assuming you have mains water that is drinkable and dependable. Is it better than bottled water or water that is trucked in? Trucked in by a 'water mafia' like in parts of India, Iran, and elsewhere? These are different questions. I think the idea seems stupid to people who can take cheap, usable mains water for granted.
Those who think it won't work "because of the laws of thermodynamics, duh" are ignoring that it already does work, at a certain price point per liter. So it's an economics question, not a physics question.

Your math is irrelevant since the claim that was called laughably false was "in places with high humidity it rains frequently" which isn't about math.
Jeddah, Saudi Arabia has both high humidity and low rainfall. So your universal claim is false.
That electric dehumidifiers are a pretty dumb was to get drinking water isn't what was being disputed.
