Oh, please, you can't get rid of the observer here, otherwise it doesn't make any sense. The concept of value doesn't mean anything if there is not at least one human being involved. Same for colors, sounds, and so on. If you want to think things like this then it's a bit like the old lame debate about a tree falling in a forest where there's noone to hear it. I doubt anybody has ever tried to suggest a notion of value as intrinsic as the atoms the ice-cream is made of. I'm pretty sure people mean intrinsic value as opposed to trade value.
If you deny the existence of at least one observer, then the world itself doesn't exist.
