The governments of the world will use Bitcoin for their benefit, they can keep it as a reserve, they can make transactions but they will not recognize it because if they recognize it, the people will consolidate financial power and challenge the power against the government,
because the current control of the money of any country is the real power of the state and the government knows it very well if it is recognized, a great revolution in the money power of the people will happen.
So while most of the government has power, it buys and saves it secretly and when it loses power, it uses it silently but does not recognize it.
So I think the Bitcoin money and savings system is a reflection of democracy.
Bitcoin doesn't relate to system of government, it relate to the financial system created by the government. If you loo at the Bitcoin genesis, it talk about the collapse of the banking system and the bail out. It relate to the government but it's more about the freedom of finance that the government is using to limit people and how they have failed to make the bank a better place for fiat in the last decades, the fiat system is a complete failure to humanity.
If you say Bitcoin is a system government, that means we can decide to change Satoshi as the founder of Bitcoin, we can decide to change the developers, we can decide to change those people that running the node because regardless of the system, whether it's anarchy, kingship or anyone, there must be a change. However, Bitcoin is more about the freedom of financial, where no one can controls about what we do with our money and how we do with them.
