The fundamental purpose of the state is to serve the public, which has consented to the state's regulatory role to dispense justice.
The problem arises when the state becomes too large and bureaucratic, taking on a life of its own. Such a state then operates for its own survival, where the people serve the state rather than the state serving the people.
Tyranny is a byproduct of such a state. At that moment, challenging the state and its very concept becomes both an intellectual necessity and a social responsibility — the highest form of public service.
People will outlast the state, and whatever comes after that.
I stick to the marxist notion to a state, which is a repressive apparatus in the hands of the ruling class.
Ultimately we should aim towards a stateless society, which at the same time should be classless.
Of course there are some social welfare features that a limited number of states include.
But it is not an inherent part of a state as experience shows. Remove social welfare and the state still persists in its distilled form of bureaucratic and violent control of common people. By means of repressive legislation, police, army.
State is a product of choices by the people. Its existance does not equal tp the existence of governabilitty. Tje conditions of state and governability do not imply their nature, i.e. authoritarian or democratic. The existence of state is to preserve the state itself, and its masters, not to serve the people as you speak unless they are the masters themselves.
