Read the following academic passage and answer the question below:
[Paragraph 1]
The legal architecture governing off-Earth commercial activity rests upon a foundational tension embedded in the 1967 Outer Space Treaty (OST). Article II of the OST definitively prohibits "national appropriation by claim of sovereignty, by means of use or occupation, or by any other means," establishing celestial bodies as a global commons. However, the treaty remained strategically silent on whether the extraction of abiotic resources—such as water ice from permanently shadowed lunar craters or rare metals from near-Earth asteroids—constitutes prohibited national appropriation or permissible non-sovereign utilization. This statutory ambiguity was sustainable during an era when space exploration was exclusively state-funded and exploratory, but the rise of commercial space enterprises has forced legal theorists to confront whether celestial resource extraction can be reconciled with international non-appropriation norms.
[Paragraph 2]
A major attempt to resolve this ambiguity occurred in the 1979 Moon Agreement, which explicitly designated celestial bodies and their natural resources as the "common heritage of mankind." This doctrine envisioned a mandatory international regime to govern resource exploitation and equitably distribute financial benefits, particularly to developing non-spacefaring nations. However, this redistributive framework encountered fierce resistance from major spacefaring nations, who argued that such centralized international oversight would disincentivize the massive capital investment and technological risk required for deep-space missions. Consequently, the Moon Agreement garnered negligible ratifications, leaving the international community without a universally accepted multilateral mechanism for commercial lunar or asteroidal mining.
[Paragraph 3]
In response to this multilateral impasse, several domestic jurisdictions pioneered a unilateral property-rights framework. Beginning with the United States Commercial Space Launch Competitiveness Act of 2015, followed by legislation in Luxembourg, Japan, and the United Arab Emirates, domestic statutes decoupled resource ownership from territorial sovereignty. Drawing an analogy to maritime law—where the high seas cannot be claimed by any nation, yet fish extracted from international waters become the lawful personal property of the harvester—these laws grant private entities full property and commercial rights over extracted space resources. Proponents contend this maritime analogy reflects customary international law, permitting unilateral appropriation of resources while fully respecting the non-sovereignty mandates of Article II.
[Paragraph 4]
Nevertheless, the high-seas extraction analogy exhibits acute limitations when applied to the spatial realities of celestial bodies. Unlike pelagic fish stocks dispersed across vast oceanic expanses, commercially viable celestial resources are concentrated in hyper-localized, irreplaceable sites, such as the water-ice deposits situated on the lunar south pole's "peaks of eternal light." A purely unilateral extraction regime inevitably risks de facto territorial exclusion, creating severe regulatory conflicts and tragic resource degradation. Therefore, rather than relying exclusively on fragmented domestic property authorizations or resurrecting an unworkable global redistribution bureaucracy, the international community must establish polycentric coordination compacts—adaptive, multilateral safety-zone protocols that validate private extraction rights while equitably managing access to scarce, congestion-prone landing and mining sites.
Match each paragraph of the passage to its primary structural function in advancing the author's central argument.
- Paragraph 1Identifies the core legal ambiguity in foundational space treaties that commercial expansion has made urgently necessary to resolve.
- Paragraph 2Describes a failed multilateral attempt to manage resource extraction through a centralized redistributive regime and explains the basis of its rejection.
- Paragraph 3Examines unilateral national legislative approaches that authorize private resource ownership via an analogy to high-seas harvesting rights.
- Paragraph 4Exposes the physical and regulatory flaws of the maritime analogy and advocates a balanced multilateral coordination framework as the primary solution.
