The origins don't matter, every civilization, region, and town made its own system, I'm referring to the fact the the US and the UK are the only developed nations that still USE imperial, when there's an easier, widespread, more sensible system available right next to it.

That's not a strawman fallacy as I didn't deny your input by miscategorizing your personal value, if anything it approaches a bad reason fallacy or an antecedent denial fallacy, but it's neither because we both made our points of view on separate foundational assumed beliefs without addressing proofs or evidence. One could also throw an appeal to emotion or an appeal to ridicule fallacy in there with my silly joke about imperial units but we're not debating a verifiable, objective truth. Neither are we attempting to find some higher level of human understanding of our spaient peoples world, we're just wasting time on an internet forum, as in "they're just opinions, man."

Every unit of measure that humans created to measure the world we live in, like metric and imperial, is human-intuition centric first. Imperial units were created just as formally, and informally, as metric. The imperial system is based on a different system, based on another system, that was based on the science at the time used for pharmaceutical, military, and crafting applications. Just because imperial used hands and feet of SOME guy doesn't make it less or more arbitrary than the measure of "one liter of water." A system, based on a system, based on science at the time that is just easier to understand in the base 10 system we live in.

The 0 - 100 hot-cold argument for Fahrenheit is just incorrect. It was made by SOME GUY and 0° was the freezing point of HIS brine in HIS basement. 0 F° isn't cold, it's deadly, and 100 F° is not. That seems just as arbitrary as 0 - 40 C°. If the scale was the same people would actually refer to Celcius as -32 - 40 C° instead, and that's just not the case. Decimals are not scary, they're equally simple to use by any person who uses the base 10 system, unless the argument is that people who use Fahrenheit also struggle to make change when handling money.

Measurements are not one-to-one comparable to language, but when most people who are familiar with both tell you that one is clearly superior, and most of the world's educated people agree, and it's an easier system for children to understand, then it's fairly safe to call one system better. Maybe some languages are better at one thing than another, but language is interpretive, flowing, changing, adaptable. Measurements are not, they need to be universally, unambiguously understood.
