That's his lie or marketing. 
Dolarize means the central bank won't need to print, he means that and this is the start of his lie.
The central bank has another core job, be the insurance of the banks like we saw with the American banks. So he propose to "shut down"(no more printing machine) but he will put a "regulator", just an insurance for the banks.

About the socialism, he won't touch the "social plans" (free money for the lazy people) cause they are the "victims of the gov". He can't touch this cause he wanted their votes and cause he doesn't want riots.

He is just a big mouth, nothing will change cause I know how they steal the money. You can change the heads but if you don't change the core, they will keep stealing. 

 That’s quite the bleak outlook. I hope for Argentina’s sake that your are mistaken. 

 He is economist, he loves the dollar.
That means he plays for the financial system and rich people.
He never explained what's the money, like every politician in the world.
