What is the optimum role of government in a capitalist economy

In a capitalist economy the job or role of government is to make the national defense stronger, maintain law and order, and regulate the money supply. The government does not have a huge role in this type of economy.
Hope this helps Xx :)

In a capitalist economy, the role of government is very limited. The main functions of government, as given by Adam Smith, are to maintain law and order in a country, make national defense stronger, and regulate money supply.
