>And why should we anyway?

Because the environmental cost of producing, shipping and disposing carbonated drinks is nearly incalculably higher than just drinking tap water? Even you add a post-tap filter stage it's still magnitudes less impactful.

This is absolutely valid. I do welcome diet sodas as an alternative to regular sodas, but that concerns health outcomes, not environmental concerns. This problem applies to any drink that isn't tap water (including bottled water), so it's a separate discussion to be had from artificial sweeteners.
