Water bottles or not?

If I had a choice to choose between having water or  not, I would say that we should not have water bottles because water bottles have bad chemicals in them and you can get water for free at bubblers. Why would you pay for something you could get for free? There is a reason we have bubblers, it's because people can't afford water and even if you can there is no point of getting a bottle that you will throw away and ruin the environment. There is a way to save our planet and it's not using water bottles.
