How can a technology make the state's monopoly on violence obsolete?

In my opinion the best response I've seen to any state monopoly on violence is the US Second Amendment.

I guess 3d printed guns are a technology built around this same principle of empowering non-state actors to arm themselves. If everyone were armed, no one could have a monopoly on violence.

Is that the kind of freedom tech you had in mind? 

 Honestly I have no idea. But 16 years ago I also had no idea of how a technology could make money debasement impossible. 

But to answer your question, no, this is not what I had in mind. I don’t mean fight back. I mean something that would make us immune to state violence just as Bitcoin makes us immune to money debasement or nostr makes us immune to censorship.
