People think Javier Milei was elected by his people because of a mass movement, and a dismissal of far left values.

This is only partially true.

The reason the election was allowed to happen the way it did, is because Milei said he would base the new Argentine economy on the U.S. dollar, then he drove through the street waving the flag of Israel. Thus he appeased the two governments who are most dangerous to up and coming politicians.
