Yes, not only Argentinians, but people in general can endure lots of grief if they think it's for a purpose. That's common nature, and something with counted on blindly. Here crisis is a day-to-day reality so not only not much changed for the majority of people, but since public spending was slashed on the parasites, Milei voters are only seeing the benefits of the consequences which is decelerating inflation and increased freedom through deregulation. That, plus the permanent public disclosure and dismantlement of previously hidden parasitic state structures and state mobs, as only lead to a permanent increase of his image. Literally most people will tell you "I don't care how bad it gets, as long as he makes those despicable criminals pay". The situation is bad but no one is scrapping the barrel, and everyone in a vulnerable condition is still receiving full support.

Literally no one that voted for him ever thought "one thing is to vote him but other to actually let him do what he says". All the opposite, the one great fear his voters had, a question they made to me permanently, was: "do you think he will fulfil his promises?" Seeing him doing what he said has only gained him more supporters than during the election.

That leads to the answer to your last question: it's a given that he will get the majority he needs next year, I'm not even worried about it. The process has started and it's irreversible. My only worry is to make my part, to underpin the rise of libertarianism as both a political force and a philosophy of life.

About Bitcoin, yes, it's going to be declared legal tender. But remember that that only means that the government will start accepting Bitcoin as payment. Bitcoin is already a usable day-to-day currency here, and I personally live that way. It's not only fully legal to have and use, but even more than that, it's completely outside of the radar by any means, so there are legal and registered service providers which offer superb usability services.
