How does Ayn Rand’s nonaggression principle limit the proper role of government?

Ayn Rand’s political philosophy is centered on the principle that no individual has the right to initiate the use of physical force against others. This "nonaggression principle" serves as a strict boundary for the state, dictating that the only legitimate function of government is to protect the individual’s inviolable rights to life, liberty, property, and the pursuit of happiness.1

Because Rand viewed the initiation of force as fundamentally immoral, she argued that this principle is incompatible with government-mandated redistribution of wealth, social welfare programs, and most public services. She maintained that such institutions inherently rely on the threat of government force against those from whom resources are seized. Consequently, Rand advocated for a system of pure, unregulated laissez-faire capitalism, which she believed was the only socioeconomic framework that fully respects individual property rights and adheres to the nonaggression principle.1
