You start out telling us how you lost $4,800 worth of bitcoin, purely because it is a virtual currency, then tell us how “immutable” it is, and how it will replace real money. No problem: just make it illegal for banks to deal with bitcoins or other virtual, made up currencies. Problem solved; bitcoin value returns to zero.
How this is supposed to end the Nation-State is not made clear: apparently you think the only thing governments do is print money, and defence. There’s a few other functions that people find worthwhile: border control, policing, public Education, Health, and welfare, for a start. If you think the nation-state will wither away, and you think that is a good thing, consider those territories where the government has withered away: South Sudan has zero government, and going down the list they become slightly healthier, but are certainly fragile if not failed states.
