> suck wealth out of the US it would be criminalized yesterday.

until the USD is not the dominant reserve, USD themselves is considered wealth. You cannot suck wealth out of an infinite fountain.

So the time when the US gov't would institute such controls would be if China's dominance continues to grow, until chinese currency (whatever it may be - digital or fiat) is the new reserve. Because USD at that time would have become worthless.

I would bet nuclear war would occur before that.
