it's two stated:
Libra will miss the current global monetary system.
In fact, it doesn't matter if it's called Libra or otherwise, whether it's made by Facebook or someone else. In any case, the resistance of the ruling elites will be extreme. Therefore, "well-rounded" worries, withdrawals, and so on. The pressures are too great, and things are going on in public.
What do they want to do when currencies are NOT Banned, let alone destroyed? They can ban Bitcoin but they can't, Libri can ban it and it won't, Bitcoin will continue to function as before, the price would probably drop, but nothing will happen.
