Which has it's own monetary, energetic, and potential social cost. A potentially not so small cost, too. Depending on location and climate change.

Inexpensive chemicals like sodium hydroxide/ bicarbonate also prevent limescale, avoid producing chlorine, etc...but then you end up with salty/alkaline brine. Which might be the true issue here, how to dispose of industrial quantities of that.
