Read the following excerpt discussing nineteenth-century legal doctrine:
In analyzing the constitutional legitimacy of state-mandated price caps on grain storage facilities, nineteenth-century American jurists frequently invoked seventeenth-century English jurist Sir Matthew Hale’s treatise *De Portibus Maris*. Hale had posited that when private property becomes 'affected with a public interest'—such as a solitary wharf enjoying a natural geographic monopoly along a navigable waterway—it ceases to be *juris privati* alone and becomes subject to affirmative public regulation. Legal formalists sought to restrict Hale’s doctrine strictly to enterprises possessing de jure state franchises, arguing that private warehouses operating without explicit sovereign charters fell outside state police power. However, progressive jurists countered that Hale’s primary concern was de facto market dominance rather than formal governmental privilege; by drawing an analogy between a modern railroad junction's grain elevator and Hale’s monopolistic river wharf, these judges demonstrated that extreme economic bottlenecks create identical vulnerabilities for public commerce, thereby justifying statutory rate oversight even in the absence of explicit municipal monopolies.
Match each cited phrase from the passage with the statement that most accurately characterizes its primary rhetorical function in the argument.
- a solitary wharf enjoying a natural geographic monopoly along a navigable waterwayServes as an illustrative archetype defining the physical and economic conditions that subject private property to public regulation.
- enterprises possessing de jure state franchisesIdentifies a restrictive category advanced by formalists to constrain the scope of legitimate state intervention.
- drawing an analogy between a modern railroad junction's grain elevator and Hale’s monopolistic river wharfActs as a methodological bridge extending a historical common-law precedent to modern industrial circumstances based on structural equivalence.
- extreme economic bottlenecks create identical vulnerabilities for public commerceArticulates the core substantive rationale justifying regulatory oversight over vital market choke points.
