If a nation has a strong, moral culture and a strong, moral people the state is unnecessary, the culture of the people is enough, but the state can destroy the culture, civil society, and the people that makes the nation great.
If a nation has a weak, immoral culture and a weak immoral people, the state will inevitably be corrupt, and will destroy those few strong, moral people left.
The state is at best unnecessary, at worst, a corrupt, mass-murdering destroyer of culture, morality, civil society, and people.
