The solution seems so simple to me: drop the ARS and use USD as the national currency. Your inflation is just trying to pay for goods and services using an eternally depreciating asset (the Argentinian peso).
The reason this doesn’t happen is because it would mean that the Central Bank of Argentina (CBA) would no longer be able to, at will, monetize the debt of the Argentinian government and favored corporations. Ie. the CBA would lose its ability to purchase a government bond in exchange for crediting the government’s account with the face value of the bond — convert debt into money.
At the end of the day it’s a conflict of interest: the people want a stable medium of exchange and the government wants to finance its activities without balancing its budget.
The economist Melchior Palyi explained this phenomenon in his 1962 book “An Inflation Primer” following the high US inflation of the 1940s: https://cdn.mises.org/An%20Inflation%20Primer_2.pdf
