If something is available in the ocean, it doesn't necessarily mean that it can be extracted easily. we can say that it is abundant etc. But it cannot be concluded that it is cheap. Extraction costs are unknown. Also, the fact that it is present in extremely low concentrations implies that extraction could be costly. Easily = Cheap. Most extraction processes can go very expensive
