But WW2 ended colonialism and 90s globalization spread industrialization worldwide, leaving us all in the slow roll of reverting to the mean now. At the end of which, the ancient civilizations of China and India, with nearly 3 billion people between them, will return to global dominance.
That's what we're headed towards. The 'dark enlightenment' fascists think they can accelerate a switch of global banking moving towards cryptocurrency. Good fucking luck trading a bitcoin when normal finance is blowing up, grocery stores are going to struggle with stocking their shelves.
Also, if crypto would be to become any money, then it would not produce any yield in average. So it would not be interesting to hold, the whole scenario makes no sense.
All of the dark outcomes you describe are possible while a certain class has profitted already so much they don't care and will happily retreat into their bunker.
