Sounds interesting. It sounds like corporate feudalism, which did seem like a realistic scenario we were heading towards, but I don't think so now. In a hyperinflationary scenario like mentioned in the article, it's large institutions especially corporations which would be least well able to adapt. Fiat currency is the lifeblood of a corporation, everything relies on it, as well as respect for private ownership, which would also likely be undermined. The larger the institution, the harder it is to adapt to alternatives like cryptocurrency quickly.
I also find this line pretty funny:
Hyperinflation has also negatively affected much of the rest of the world (with some exceptions like Japan)
A little ironic given that Japan currently is the most aggressive in monetary policy of the developed world nations, with negative interest rate policies and persistent monetization of debt.
It sounds similar to Ghost in the Shell, but that seems to be a different kind of feudalism (ie. multiple factions of the deep state rather than corporations). But I think both would be seriously undermined by a hyperinflationary scenario. IMO, fascism is the most likely form of state to be able to survive or arise from hyperinflation, because a nationalistic fervour and threat of violence is something which can still motivate individuals and groups when money itself is failing. But cryptocurrency may allow smaller institutions to keep working effectively without a functioning state, and does provide an alternative outcome.
