Explanation:

The role of the government in any nation (traditionally) is summarised in the following major categories:

1. Defend the Natural Rights

2. Protect Against External Enemies

3. Managing Economic Conditions

4. Redistribute Income and the States Resources equitably  

5. Provide Public or Utility goods

6. Prevent Any Externality

Printing Money comes under item 3 - Managing Economic Conditions. If people were allowed to print money, there would be an excess of it in circulation and that would lead to a quick erosion of the value of the same. One of the qualities of money is that it must be scare.

The purpose of the Navy is to protect the state from intrusion via its waterfronts. This falls neatly under item 2 above - Defend Against External Enemies. Other functions of government that fall into this category are Policing, Creating and Managing the Army, the Airforce, and even the Customs.

Creating a post office, issuing driver's licenses, and establishing a public educational system all fall under the duty of the government to provide Public or Utility Goods.
