You might be confusing debt issuance with money issuance.
Governments often issue debt to fund various kinds of spending. And despite concerns about debt levels, they can have a pretty fuzzy relationship with inflation; Japan has public debt of over 200% of GDP, and an underinflation problem.
But issuing money for the purposes of government spending – the monetization of fiscal policy – is almost always a bad idea, outside of wartime. The practice is behind every single episode of hyperinflation in economic history. And governments know this. Fiscal monetization is only resorted to by countries that have exhausted their ability to borrow; if cutting spending isn’t politically feasible, the remaining resort is monetization. That’s basically how you get to Argentina’s situation.
As for giving up monetary autonomy, it is indeed a serious drawback to dollarization. But this is a second order problem compared to the kinds of problems facing Argentina, like findng a guy bleeding out after a road accident, and worrying about his obesity.
