U.S. monitoring of the global flow of money is frankly terrifying. U.S. law enforcement is currently politicized to an extreme degree, and the extent to which the U.S. continues in the near future to be a democracy under something vaguely like the rule of law is in severe question. One of the scariest things to think about in contemplating the possibility of having to flee this country in some point in the next few years if it goes full authoritarian is being instantly impoverished to the point of not even being able to buy gas to get to the Canadian border on the flip of a switch of some faceless bureaucrat.
