Although Columbus is criticized for the exploitation, enslavement, and suffering associated with European colonization, his voyages offer an instructive example of the risks of investing in exploration. In 1492, Spain's monarchs financed an expedition to find a commercially valuable route to Asia, uncertain whether Columbus would succeed—or even return. But there was another risk: would he be able to claim the rewards of a successful voyage? The Capitulations of Santa Fe promised Columbus hereditary privileges, including the offices of Viceroy and Governor of the territories he discovered. Yet the Crown subsequently removed him from office, and after decades of litigation, his heirs lost their claims to those hereditary governorships. The Treaty of Tordesillas of 1494 sought to reduce another source of uncertainty by dividing overseas claims between Spain and Portugal, although other nations and Indigenous peoples were not parties to the agreement.
Five centuries later, companies exploring the ocean floor face similar uncertainties. ABC News reports that some companies hope to recover valuable nickel, cobalt, and other minerals from the deep ocean. But collecting minerals thousands of meters underwater is technically difficult and commercial profitability remains unproven. In August, NOAA announced that it had advanced its review of an application by The Metals Company to explore and commercially recover minerals from the Pacific seabed. Even if the technology works, property rights remain uncertain. The United States has its own permitting process, but the International Seabed Authority maintains that mining in international waters requires authorization under its international framework.
Both ventures illustrate two distinct risks of exploration: the technology may fail, and even if it succeeds, (perhaps because it succeeds) the claim to the rewards may fail. The expected return on investment depends on both probabilities. Property rights are valuable only to the extent that they can be enforced.
