If price=value by definition then that means there is no such thing as market manipulation, buy definition. And that the value of exchange traded tulips was in actual fact enormous at one point.

The fact that arbitration actually exists is because there is a disconnect between price and wealth generated solely by information differential.

And beyond an exchange, that, merely because their parent's opportunity cost differs greatly, raising one infant is in fact vastly more valuable than another essentially identical infant.

I would suggest that price is not identical to value, it's just that the market is usually the best way to determine a value.
