I agree that value is subjective, but value is still created by labor.

Sit and stare at a rock and you have created no new value.

Labor can also destroy value, for example when a building is destroyed in a riot, or when a rock is pushed up a hill to a location that makes it less valuable.

Trip over a sufficiently shiny rock and you'll discover that it has value (to some people) even though you put no labor into it.

yes, a very small amount of readily available (labor free) raw material has value to some people

but most raw material requires applied labor to become valuable: at the very least transportation to them
