Give two reasons why mercantilism would be an unrealistic economic policy for a country today?

Firstly, mercantilism promotes a zero-sum view of trade, where one country's gain is another's loss, which contradicts the modern understanding of global trade as a mutually beneficial exchange. Secondly, today's interconnected global economy relies on free trade and competition, which fosters innovation and efficiency, making the protectionist measures of mercantilism counterproductive and likely to lead to trade wars and economic isolation.
