So you can compute the " change " in total surplus using just the marginal seller and the marginal buyer.
2.
The point on the seller curve is actually the cost to the marginal seller at this point, because at that price, he stops producing.
3.
The marginal buyer ( the extra person who bought some pens ) and the marginal seller ( the extra person who sold them ) will have a loss of surplus.
4.
So while it may be true that " at any quantity below the equilibrium level, such as Q1, the value to the marginal buyer exceeds the cost to the marginal seller ", I don't see what that has to do with consumer surplus ( or producer surplus ), because there's no reference to prices.
