If you buy 5 apples from me for $5 then two things must be true: 1. The value that those 5 apples have to you exceeds the value that $5 have to you, at least at this very moment. Otherwise you would hang on to your $5 instead. 2. The value that those 5 apples have to me is less than $5 have to me, otherwise I would hang on to the apples.
The price of those 5 apples at this moment may be $5 but that doesn't reflect the value they have to neither me nor you. It's not the avereage either, necesarily. The only thing we know is that the value of them to you is higher and to me is lower.
Not necessarily. You could have a transaction take place where the buyer and the seller both value what's being exchanged in exactly the same amount and then go through with the transaction anyway because they both find trades entertaining or have a cultural preference for doing business with each other or just both place zero value on transaction costs.
That isn't common but that doesn't mean it could never happen.
