Okay, so I have a hypothesis that Milei is doing all this with his eyes wide open, That's not an endorsement, by the way, just an observation. Milei is an avowed libertarian anarchist capitalist, no?
Libertarian approximates to "get your government out of my business;" Anarchist approximates to "We don't need no steenkeng government" and what is Capitalism is left as an exercise for the reader.
Back in the 2000s, I'd say that it wasn't the Kirchner's who kickstarted the Argentine economy back to life, it was the world demand for what Argentina produced, the rise in the market prices and the willingness of the Argentine people to put the dreadful events of the time behind them. The Kirchners just took the credit.
There were at least two British politicians of the 80s and 90s who had been finance ministers yet admitted afterward that their policies made no real difference to the economic outcomes of the country: all they were really able to do was watch from the sidelines and when things went well, claim their policies had won the day but when things went badly just shrug and blame world events. The policies, they said, were just window-dressing. Even Napoleon recognised the inevitability of things and, far from forcing the population to do his will against their desires, was shrewd enough to sense the direction of the popular groundswell then place himself at the front and lead the people where they were already headed.
So now, here we are, with world events predicting a rise in commodity prices and weather events predicting some bumper harvests in Argentina over the next couple of years and all Milei has to do is stand back, watch what happens and wait to take the credit for what would have happened anyway.
Or blame external forces if it all goes wrong.
