The advent of currency took them to a whole new level, though. Graeber describes the new social structures around currency as a "military-coinage-slavery" complex in his book Debt.

I still fail to see how bitcoins would let us get rid of either crime or war, nor downsize the army or LEOs. Same for the "conventional power politics", it's hardly a new thing, put a 100 random people on a island and you'll see the same mechanisms at play.
If a currency were to arise with no political group can control, this mechanism of domination would be short-circuited. I don't doubt that there would still be organized violence, but there's good reason to hope it wouldn't be on the scale we see today.
