I didn't make that argument. Fahrenheit is more natural in a lot of cases because of the range and delineation between whole number temperatures. Celsius is slightly less so but not all the time.
My entire point, which was lost in the bikeshedding is that it is not "shocking" that the metric system isn't used everywhere in daily experience because non-metric systems were literally invented to be useful and practical. Are they perfect? No. Neither is the metric system for daily human use.
The U.S. is a big place and thus has wide-ranging temperatures, and that probably contributes to resistance to getting rid of Fahrenheit, amongst other things and other measurement systems. The U.S. built a huge amount of modern infrastructure before anyone else and has never experienced a "rebuild" period. For non-engineering purposes, there's no downside to using non-metric units, and a lot of downsides in converting. As the back and forth here shows, there's probably a strong argument to be made that the measuring systems don't matter at all in an ideal world where it's free to convert entire countries back and forth between them. But for some reason, a lot of the world feels very superior for using the metric system.
Again. Not "shocking" as the original comment I replied to mentioned.
