Final answer:
Libertarians indeed favor minimal government interference in economic markets, aligning with laissez-faire principles for increased economic efficiency, affirming the statement as true.
Step-by-step explanation:
Libertarians typically advocate for minimal government regulations and support the idea of unfettered markets for the sake of economic efficiency. This ideology aligns with the principle of laissez-faire economics, which suggests that the less the government is involved in the economy, the more efficiently the market can operate. This viewpoint is grounded in the belief that the private sector is more efficient at resource allocation and responding to consumer demands than governmental intervention could be. Therefore, the statement that 'Libertarians favor unfettered markets and oppose government regulations in the name of economic efficiency' is true.
