Quote from oldtime:
Until we live in a one world government, it's just like they teach you your first day at plumbing school, "Money, like water, will always seek it's lowest level."
It is happening now. It is called grey economy or black market. Trading and speculation will always exist in one form or another. It will move off regulated exchanges or to physical goods and currencies. And maybe that is what they want - corruption and black market. They can steal more tax free.
