Answer:
- A well-organized police force.
A functioning government depends on a police force to enact its laws, and to persecute those who do not follow them. The police also ensures that the government has a "monopoly on violence," one of the basic requirements of a state. Finally, the police also provides assistance and protection to citizens.
- Interstate commerce regulations.
Commerce fulfills many needs of society. It redistributes goods, encourages cooperation, provides a source of income for people, and connects different regions. However, unregulated commerce can be a problem for the government. Therefore, commerce regulations are necessary for any well-established government.
