Money is a huge leverage point for the government to use to manipulate the populace. I agree this doesn't "solve" tyranny in large, but does take one piece out of the equation, money.
Next is censorship and government approved speech. Nostr takes this piece out of the equation, free speach.
Lastly is taking away ones ability to defend themselves but 3D printed guns and ghost guns takes this piece out of the equation, right to bear arms.

That being said tyranny is still not solved but it is kept in better check than before these technologies. To your point though, hopefully not that many bitcoiners are voting for Harris. 

 fundamentally it is up to the people to secure their rights from being taken by the government. A government cannot grant rights, only take rights, as the default position for humanity is absolute freedom. As history has shown the government will try to take liberty away from individuals in effort to keep an elite group in power under the guise of "security".
