We aren't talking about galvanized pipes. We're talking about distilled water in large amounts being bad for you. If you feel that what the WHO and Neil DeGrasse Tyson said is inaccurate or misleading, then I'm sure there are various ways to contact them and see what they have to say. There's only so many ways I can explain things to people before it gets tiring. Have a good day.
You're talking about a carbon steel wrench that rusted away on the bottom of a stainless steel tank due to Galvanic corrosion. It is an extremely common problem for submerged metals. It is usually mitigated by sacrificial zinc anodes, which are slowly dissolved byb the water, protecting submerged structural and mechanical conponents of boats, ships, pipelines, and structures.
The claim from that article is bogus. It was written by someone who does not understand what they are talking about, for an audience that doesn't care.
Rust and corrosion โ dissolving. We don't say that we corrode table salt in water. Like I said, if you think that you know better than the World Health Organization and Neil DeGrasse Tyson on this topic feel free to contact them and see what they have to say.
Neither WHO nor Tyson claimed that pure water dissolves metal. That claim came from an article you linked about a Japanese science project, which uses a large tank of pure water as part of a neutrino detector. The entire article was a B-story to that neutrino detection project.
Between the author and the translator, the distinction between "dissolve" and "corrode" went missing. Context restores it for anyone who recognizes the conditions present in that tank. That was simple galvanic corrosion, not some mysterious property imbued on water by distillation or reverse osmosis filtration. The exact same process occurs within fresh water and within water in which considerable amounts of electrolytes and minerals are dissolved (salt water).
