The government would then only allow and control the single IPv6 address into the country... I may be unaware of part of IPv6, but my recollection is that it allows for more addresses due to a larger format. It doesn't look like that would solve this problem. The issue here lies in the very small and controlled pipe into the country, not with the network running on either side.
