1. It's not a must that you mine to sky-rocket the price, buying means volume and volume means price movement
2. You will always need to hide your money if you play it dirty or to pay less taxes.
3. Regarding internet restriction, there will always be a way to access the net. Plus, don't forget physical bitcoins and Localbitcoins or persons selling bitcoin in person for cash.
4. Regarding North Korea, check Localbitcoins volume in Russia
Errors :

2.
There is not no internal bitcoin black market
3.
Third I doubt that in those countries are to too many the people with big money which have no power and need to hide its their money.
4.
Four, you must read the restriction they had in on internet and the possibility of access on accessing it by the normal people.
5.
Five, you must understand the power of political dictatorship on in these countries and the enormous fear that this nomocracy raise to everyone in doing not allowed restricted things.
