Why are reefs so expensive?

Why are reefs so expensive? It's a question that has puzzled many individuals, both in the field of finance and beyond. Are reefs inherently valuable due to their unique ecological and biological characteristics? Or is it simply a case of scarcity driving up prices? Some experts argue that the intricate balance of life within reefs, as well as their role in supporting marine ecosystems, contributes significantly to their worth. However, others point to the limited supply of reefs available for purchase, which they say is a major factor in driving up prices. What do you think? Is it the inherent value of reefs, or the scarcity of available options, that makes them so expensive?
