Final answer:
Anarchy is the political system that matches the description in the question, as it represents the absence of an organized government and authority, contrasting with democracy, monarchy, and oligarchy.
Step-by-step explanation:
The political system described in the question seems to best match the definition of anarchy, which is characterized by the absence of an organized government and authority over others. Anarchy negates the power typically exercised by a state over individuals within a community. This concept contrasts with other forms of government like democracy, where all citizens have an equal say in state policy; monarchy, where a single ruler typically holds power by hereditary succession; and oligarchy, where a select group of elites governs.
The key difference lies in the role of individuals and state authority within the community. In an anarchy, there is no formal state to impose control, rendering each individual autonomous and without the imposition of authority by others.
