Why do people keep thinking it's the currency's job to enforce law and order? Currency is just for trading. Other systems should be in charge of justice (and already do).
With bitcoin, most people's mindsets are for everything to be decentralised. Justice is extremely centralised right now, much like this forum (just check out meta). So hmmm.
Doesn't matter. Decentralized justice is still not the currency's job. We should be creating a new system for that.
