Of all the problems you listed, only the "colonel" is ~unique to Brazil. Every single one of the others is something a country of any size has also faced, and solved, without introducing black boxes into the system.
Well, since I took the time to answer your previous question with many examples of issues and you seem to think they have been solved, why don't you go through my list and explain how you would solve each of them, or how you have seen them solved?
That would be helpful, and would be the polite thing to do. Simply saying they have isn't.
Also please note the last paragraph on my post. It's an important one.
Also remember, the black box is heavily audited and signed off by all interested parties. There's plenty of space for improvement, but it's not only good enough but it's also much better than what I observe everywhere else and our own past.
