Nothing? I referred to a fantasy, not reality. (Don't get confused.) It's possible I missed one of the cautionary tales I was supposed to catch to truly inculcate the proper American fear and hatred of foreigners. If you can point me to some 1980s-era capitalist propaganda that features this particular horror, I'll concede the point.
Back in the real world, it seems possible that e.g. China already has this, or will soon. I wouldn't take either side in the "is China communist?" argument, for fear of offending. I don't care very much, because I don't live in China. I'm concerned with the particular drain that my own nation is circling. You apparently share my apprehension; otherwise you would have argued that this wouldn't happen here rather than that it will also happen there.
What's preventing a "communist hellhole" from implementing something similar? Is it something about state ownership of capital that prevents a third party from interfering in two consenting parties from engaging in transactions? Actually, now that I think about it, aren't communist regimes pretty famous for shutting down markets? Isn't that a variant of "all transactions will require the approval of more than the two involved parties"?
