There are many jobs that get taken care of by the families, like raising children and accumulating money.
Families also answer the five questions of government.
The first question is the question of sovereignty. Who is in charge? The answer would be the parents or guardians.
The second question is the question of hierarchy. To whom do I report? In the case of the children, the answer would be the parents. In the case of the parents, they are most likely the highest power in the hierarchy of family government.
The third question is the question of law. What are the rules? There are rules. The parents decide on these rules, and they vary from household to household.
The fourth question is the question of sanctions. What does the person get if they obey? What does the person lose if they disobey? This goes hand-in-hand with question three. The consequences are also decided by the parents.
The fifth and final question is the question of succession. Does this outfit, this government, have a future? Of course it does. Without families, there would be total social collapse. The human race would die out relatively quickly.
There are also the marks of government.
The first mark is the authority to exclude (or have legal rights). They have the right to protect themselves against interference from other governments.
The second mark is the authority to command obedience form its members. Governments have laws. In families, the laws come in the form of the third question mentioned above. If the members do not follow the laws, there are consequences.
Many people do not see family as a legitimate form of government, but I do.
