Your statement that a country can devalue its way to prosperity makes absolutely no sense. Please feel free to cite an example where a country devalued its currency continually and prospered.
Argentina is not going to devalue their way to prosperity, only misery. I don't think they will prove me wrong.
If you were being purposefully obtuse and reading my statements about Argentina as referring to an individual (and given I was replying to a message about Argentina, not an individual that seems a big stretch), then yes, if an individual or small group of individuals control the printing press and prints themselves $50 billion and keeps it for themselves, then sure an individual can do so, but they will be killing their own currency unless they immediately trade it.
One cannot devalue one's way to prosperity, only to misery.
Actually, quite the opposite.
The people who have control of the printing press, i.e. the people who control whether to devalue or not, most certainly can and do use devalue of everybody else to create prosperity for themselves.
Your statement about prosperity makes no sense; it's as you think the decision makers' lives are in any way connected with the lives of their victims.
