I think you should research a lot more, and read some good books on both sides of the arguement like i did.
It's actually a good thing if water is slightly acidic, your stomach acid has a low pH and it's the over alkaline foods we eat that is causing acidosis in the body overall, and neutralising our stomach acids a bit too much. Fruit is acidic but you wouldn't say dont eat it. Although it is acidic, it has an alkalising effect on the overall body, just as distilled water.
I won't go into arguring all your points, but if you want to know more, feel free to get in touch
