It's true that Jimmy created value, but so did the people who chopped the trees and mined the graphite (or however you get graphite). But it's unlikely that Jimmy got the wood from the person who chopped the tree - they got it from someone who paid the lumberjack a wage and took the created value for themselves. If Jimmy starts employing people to make these pencils, he is now taking the value of their labour for himself, purely because he had the money to buy these raw materials in the first place.

That's ignoring the environmental impact of getting these raw materials. Value creation doesn't happen in a vacuum, and most people involved in the creation of that value don't get a share in the profits from creating said value.
