What's the point of being considered 'employed' if you can be wiped out with one trip to the ER?
All that said, the main issue with the health insurance metric is that it would end up being a forcing function for the continued coupling of work and healthcare, which is bad and toxic.
But oddly this doesn't seem to be how the concept is typically framed.
My second level curiosity is how much cheaper/competitive it'd be if we had space elevators.
Even the opening example—like if Alice said something truthful but offensive or bombastic, and Bob objects, Carol can say "Well, she's not wrong..."
Back when Americans economically feared the Japanese rather than the Chinese, there was a myth that the Japanese were so conformist that the same word meant both "to differ" and "to be wrong"—chigau (違う). Well, Japanese society is pretty conformist, ngl, but the reality is a bit more subtle. In Japanese it's incredibly rude to tell someone they're wrong so instead they say chigaimasu, "it's different".
That said, it's true that certain flavors of US English, like marketing speak, will avoid many phrases in this family.
This is because many American English speakers will see expressions like this, particularly when not used in a directly complementary way, as either bureaucratic and avoidant or slightly pedantic or both. Because for many Americans, leaving ambiguity implies lack of confidence in the statement or evasiveness. (At the same time Americans also know not to trust confident statements - they are separately known to be "snake oily" - but we still tend to see marketing that avoids directness as even less trustworthy.)
So this mode of expression is much more common in personal speech.
