People depend on one another to provide goods and services. This is known as a market, where all people are dependent on each other for their survival. This is in contrast to independence, where an individual is dependent on themselves for their survival. This is known as a state of nature. A completely independent individual will need to be self-sufficient in order to maintain survival and independence, thereby limiting what they can do with their lives. An individual can accomplish more when independence is tempered with interdependence. This is why markets are formed, to supplement independence. The problem with the market is that it is vulnerable to people who would exploit the interdependence of people for their own unenlightened self-interest, that is, using the threat or use of violence to establish forced dependence. This is known as government, where certain people are dependent on others for their survival but do not contribute anything of value in return.
