Andreas Antonopoulos made a good point that a "countrycoin" would always have a trusted key held by the country's monetary issuing authority which would basically then provide an enormous honeypot to tempt attackers to target it/steal it. OTOH, currencies like bitcoin with fixed monetary policy don't have a backdoor mechanism for money creation (without overwhelming consensus to fork). Also, I see Political intervention in currency as a bug rather than a feature.
