Using that definition, air too has intrinsic worth.

But I'm skeptical about the usefulness of this definition.

[Nathanba]

it's the only useful definition because what else would ever be useful just for its own sake? There has to be a reference point and the moment you have one, it's technically not intrinsic anymore. So we can't do that.

It's not because a word exists that it makes sense to use it.

The (scientific) word æther exists too, but you would only use it in a historical context.
