Bottled water is nowhere near as consumed as tap water. I can bring several cases of mass poisonings over the last decade despite being a minoritary option, while tap water remains massively more safe due to superior regulations and inspections, even if it tastes worse in some regions.
The fact is that while the chances of getting sick from bottled water are very remote, tap water is even safer, so there's no point in drinking from a bottle because somebody tells us that "it's healthier". It isn't. That's just marketing. And anybody who buys it, it's falling for it.
Now, if you prefer the taste and buy a bottle from time to time or you actually need bottled water for other reasons (be it kidney issues or running a restaurant), that's totally fine by me.
