Don't put the cart before the horse.
Hmm, quite the infidel
How would a crypto nation be anything other than prosperous?
At that stage some sort diplomatic manoeuvring and/or buying protection or starting a professional army would probably become necessary.
Buying your freedom and not really be free at all does not sound too good from my point of view.
It's like living as an expat in a foreign country, all is nice and well until that nation decides you're not welcomed anymore there since your former country wants you back for god knows what legal matter or cuts your pension. As for a professional army, times have changed, a real army that would have the capabilities of defending against one superior in numbers by factors of 5 or 10 would cost you more than bribing the entire congress.
Plus I don't know why but I can't picture a lot of the guys here would agree with paying taxes for a private army and even a lot less of them actually joining one, I've done my military service, no way in hell I'm going to a battlefield. Having an 417 under the bed in case some somali pirate thinks he's Long John Silver is one thing, open war is different.
A community near a somewhat stable and peaceful country is one thing, building and running a country in a hostile location is something else, but who knows, maybe I'm just growing to old for it.
