Do I have to fight Bitcoin if I don't want to use it? No.
Do I have to run from Bitcoin if I don't want to use it? No. -> freedom, not slavery.
This doesn't affect the analogy. Bitcoin shares the weaknesses of a democracy. But it's not an enormous concern because it is not a government, it's a totally different thing. It would be better if it didn't have these weaknesses, but there is no other proven way that could make such a system work.
Does this also reflect the claim about democracy; that it's the best one that works despite its weaknesses? Yes. Does it mean anything at all? No, analogies don't work that way. So don't worry.
That's right! Bitcoin is not a government therefor not a democracy. Bitcoin is actually an anarcho capitalist system in it's purest form. It's anarchy. Anarchy in practice does not mean anything goes. Anarchy in practice means spontaneous order and a society with some mandatory and consistent but voluntarily agreed to rules.
This idea that because people are working together and enforce certain voluntarily agreed to mandatory and consistent rules somehow this constitutes to the concept of a democracy is just plain wrong. FFS check your dictionaries.

1. government by the people; a form of government in which the supreme power is vested in the people and exercised directly by them or by their elected agents under a free electoral system.
2. a state having such a form of government: The United States and Canada are democracies.
3. a state of society characterized by formal equality of rights and privileges.
4. political or social equality; democratic spirit.
5. the common people of a community as distinguished from any privileged class; the common people with respect to their political power.
Bitcoin is a system. It has mandatory and consistent rules (they apply to everyone without exception).
But participation is voluntary. HUGE DIFFERENCE from a democracy. Democracy is a form of government participation in which is not voluntary. You have no choice but to follow their rules. Being forced to run from your home or fight against violence is not what constitutes to a voluntary choice.
