Hum… Around here water boils at ~96°C (some labs measure that). And it seems to not freeze at 0°C anywhere on Earth, as it’s never pure water, with never an homogeneous freezing point.
It is repeatable, it’s not very arbitrary, but “intuitive” doesn’t apply in any way.

You must be at altitude. That definitely makes a difference for the boiling point, but of course water freezes at 0. Impurities that you’ll encounter in tap water, for example, will not have a large effect on freezing point.
Even if it was different by a few degrees, how does that make the scale any less intuitive?
