Right. “Worth” and “price” are relative notions that are only useful when paired with a point of view. What’s your house “worth?” You might have a number in your head, but unless you have a buyer willing to transact at that price, your house isn’t worth what you think it is. And this relates to economically productive information. Your house might also be worth more if one knows that there is gold or oil buried underneath. It might make more economic sense to bulldoze the house and start mining or drilling.
