You miss the point of the discussion. The discussion is about how Fahrenheit relate to how humans interact with numbers and relate that number to temperature based on how that temperature feels.
I am not saying Celsius is arbirtray, I am saying that 40 being really hot is a weird number for most humans to associate with “hottest weather you are somewhat likely experience”. Of course if you grew up with Celsius it feels second nature. But for someone who isn’t familiar with either Celsius or Fahrenheit, the 0 - 100 could be way more intutive. Fahrenheit still fails at this because the numbers between 0-100 don’t really add up with what’s intuitive.
That’s why I said the original argument of “Fahrenheit is how humans feel” doesn’t work.
The type of building is irrelavant to the problem. Anything that works for apartment complexes works just as well for a single family house. It’s always the land underneath that’s the issue.
And at the ond of the day any solution that include getting rid of landlords comes down to the government seizing “unused” or “inappropriately used” land more aggresively. Something that just doesn’t sit right with most people.
