I'd have to say that that is the MODERN definition of government. You don't have to give up anything for security. The true and actual function of Government is to protect its people. Instead its turned into some kind of fat-cat club.
it doesn't have to be something material given up such as wealth or possessions. it can easily be something abstract. when people form governments, they give up the right of general, uninhibited freedom in return for general security and protection, as well as unity with a common society.
government exists out of the will of the people, and out of the power granted by the people to govern, and so it only makes sense that it should exist to serve the people.
i think it's pretty pessimistic to say general government has become akin to aristocracy; this certainly is the case in some areas, but not all.
