While temperature of boiling water has mostly academic meaning for everyday life, freezing point is much more important. I would say the most important temperature point for us humans. That point affects driving, walking, taking care of pipes, outside plimbing, plants, etc. Everything else doesn’t have to be that precise, 20C or 25C doesn’t make much difference. But whether it’s +2C or -2C could have huge impact.

Because of that it makes sense that it’s zero instead of some magical number that you have to compare in your head. I’ll take zero as a win for Celsius.

I mean, not really? We usually measure air temperature but ground and water are much slower to change and are usually not the equal to the air temperature. I think Fahrenheit still wins here: There might be ice on the road when the air is as warm as 40f during a passing winter warm front. There is definitely ice on the road at 0f. That’s a useful 40 degree range of increasing levels of caution.
