Having lived in countries that dollarized, formally like Ecuador, and informally like Venezuela, I can only laugh at twits like Milei who want to take the last, most unrewarding, degrading step of actually physically using that shitty currency here.
I'll gladly take any dollars off of anyone's hands who consider them a shitty currency. I'll even come pick them up in person
My personal guess is as follows:
Milei = Hard dollarization, rate somewhere between $1,000 and $10,000 pesos per dollar
Bullrich = Soft dollarization, or dual currency, pesos only used by the government, rate over $500 but under $1,000 per dollar
Larreta = Gradual removal of the cepo, preserving the peso, legalizing payment in USD, general mystery overall
Nobody else, imo, is going to be president so no need to cover their ideas.
My personal preference is an independent BCRA, getting rid of the cepo, positive interest rates (inflation + US prime + x basis points to encourage people to save/loan money here), tighter monetary supply/spending inline with taxes collected, and legalizing the payment of any debt in any
currency, but pegging things such as tax brackets, minimum wage, taxes, etc. to the value of the CCL dollar, along with peso bills in circulation so there always has to be bills worth +/- 10% of $50 USD. If businesses/people want to accept USD, RMD, Euro, Bitcoin, gold, a song, or alfajores as payment who cares provided they pay taxes to the state.
