Succesful institutional traders often talk of quitting and going to trade for themselves. Only a handful of them manage to make the transition. Most traders who leave institutions get caught up in the emotions of fear, greed, elation, and panic when they start risking their own money.
Governments are like primitive cannibals feasting on a great treasure trove of sheeple. You can't force them out, and you can't vote them out. But you can sure as hell starve them out. When enough people pick up and leave, essentially voting with their feet, it accelerates the system crash.
By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens. By this method they not only confiscate, but they confiscate arbitrarily; and, while the process impoverishes many, it actually enriches some.
