There's no proof. The proof would be if it actually happened, at which point it'd be too late to do anything, you'd just be fucked. That's the point of models: being able to make an (imperfect) prediction of the future, based on available data. It might not be right, but having a halfway-workable model is better than just going through life taking whatever comes. There's a lot that's suggestive of hyperinflation within the next ~5 years. Unabashed money-printing by worldwide central banks. Zero or negative interest rates. Massive supply-chain disruptions. Rising prices. A global economy that was shut down for extended periods of time. Yes, that would collapse the entire global economy in a few months.
