Because it is really, really difficult to get pure water. Even distilled water isn’t pure. I’m not even sure you can get pure water outside of an industrial or laboratory setting
Not very easy, even then. Very pure water will absorb CO2 out of the air to make carbonates, it will strip ions from the surface of most materials you’d want a make a distillation column from. It’s a very aggressive solvent.
