You have a point about country that have a lot of natural resources have a chance to be leading country in the future. But what is more important is what you say about crypto controlled by authorities, we are trying to run away from centralized system, not to create new one.
Countries can create their own crypto but I think people will trust more in decentralized systems. At least I hope so for that, people will have to choose to use one or another, from decisions that people make in upcoming years global economy future depends, and this time people should choose smart, in favour of decentralized coins and platforms.
If we don't make it mineable, then how? How much will be sold on person? What will be,it's market cup?
Overally your opinion will be just an unreleased idea.
How will be distributed depends from creators and developers, they can share it to all people, or they can share some and keep the rest for people in power. It's not a problem to create alt now, with blockchain that is easy to do. What is important will you trust your government and politicians behind thier coin, or decentralized bitcoin or litecoin? Where people from all over the world participate in mining? Its your choice.
