Your “proof” is incredibly lackluster. The only study it references was done on people with stage 3 kidney disease, and even the study states the conclusion might be incorrect.

Alternatively, I found a study that concludes that “consuming less than the 24-h water adequate intake may influence the risk of dysfunctional metabolism and chronic diseases” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6315424/

The study does state that the “adequate intake” is different for everyone, but at the end of the day you need to drink water. Spreading the idea that you don’t need to drink water is foolish.
