This is not a matter of perspective, it is a basic fact of markets. Market prices are quoted for small amounts. If you try to sell large amounts prices go down. If you try to sell a commodity in orders of magnitude greater that what currently exists in the world, the price drop to a tiny fraction of the quoted market price.
