Government- the Definition
Governments allow no competition with the organization and no opting out. Government is financed through "taxation", which is merely statist-speak for "theft by government". It holds a monopoly on the use of force, enforced by its own enforcers and backed up by the courts it runs. Because government enforces the rules that limit its power, there is really no limit to what it can get away with, given time.
Unless I qualify the term by placing "self-" in front of "government", I am referring to an external coercive force, and not the necessary condition of "self-control".
