In any case, this is what the IMF and the World Bank do. They lend 3rd world countries money, so much money that they know it will not have the ability to pay them back. Once this is achieved, they will have full control of that country's policies on governmental and financial matters. They will own that country.
What would occur if that country's citizens begin holding a currency which cannot be controlled? Who will have the last laugh?
This is how they work, and this is not nothing new. Money is one of the most powerful tools for IMF to control the world or to shape it as they wish, with the cooperation of the World Bank. It is almost the same situation when you as person need some money, and you can not just go to bank and get bank loan. You take money from people who have very high interest rates and they do not require any paper work. If you can not pay back what you take, they will own you and everything you have.
I am not sure that bitcoin can solve this problem, at least as far citizens are involved only. Governments could possibly switch to bitcoin, but I doubt they will do that (maybe some third world countries). We should not underestimate the big players like IMF or World Bank, power is on their side and bitcoin is currently poses no threat for them.
