The reason why Argentina has inflation is just very inconvenient to central bankers. If the pool of money increases in size, prices go up, end of story. Central bankers like to think that they can use sophisticated measures to control the economy, but it looks like they can't beyond a few simple things. Print money and you raise prices, end of story.

Central banks can't print money nor can they influence the quantity of money in the economy. The best they can do is raise the interest rate which denies people the ability to borrow.

I think this is entirely dependent on the country in question because rules around central bank operations are very different in different parts of the world. Some can directly create money and some can even seize assets.

Note that if Central bank digital currencies are allowed then Central banks will most certainly be able to influence the currency in circulation with much more power than they currently do.

This is not true. Central banks can print money (not literally print). Interest is one of their tools but not the only one.
