You might also consider retiring in Uruguay?
some advantages:
- free access to USD, in Argentina you can only convert pesos to USD at the black market for the moment (at twice the official rate).
- no yearly wealth tax of 2,25% only a tax of 12% on dividends if you have not paid this tax abroad yet, otherwise you are exempt from the tax and this tax only applies if you have been a resident for more than 5 years. Uruguay is considering lowering this tax to 7% and increasing the time period before paying this tax to 10 years:

For the reasons above, I am out of this country when the quarantine ends. (I will keep paying visits, but no way I want to settle in Argentina.)
Buenos Aires is just across the river, you can take a ferry several times a day in case you want to travel in Argentina.
