From a more practical perspective, we can all agree that there are more and less desirable states of human life, and that is the context where the term "objectively" is used in common parlance.
I reject your nihilism and substitute my subjective values as a superior model.
Maybe, but value is subjective even when you zoom in.
> I reject your nihilism and substitute my subjective values as a superior model.
I never expressed nihilism, I stated that values are subjective, and describing them as objective is incorrect and obscures the source of the practical problem you yourself described with implementing them.
There is no pink, only salmon. Got it.
Correct, they should not.
Where the statement without “objective” is uncontroversial and the discussion touches on nothing else to which objectivity vs. subjectivity is important, it adds nothing but pointless inaccuracy, when the claim is controversial or offered in a context where objectivity vs subjectivity actually matters in some other way, it is harmfully misleading.
“Better” is always subjective, so this is false.
> The issue of course is who gets to decide that
This is an issue exactly because better is always subjective.
