I'm a US citizen so it wasn't that bad for me unless I needed replacement parts without physically traveling to get them. We would just trade gifts of laptops with people when anyone was going to the US, but nothing in new packaging. At that time IIRC there was a $500 limit on how much Argentines could spend on a bank card outside the country for the entirety of a trip abroad, and obviously cash controls to prevent taking cash out and import controls on anything you brought in. The normal pattern for rich Argentines was to go to Miami and open a US bank account, then use that to buy stuff and bring it into the country in your suitcase. Fueling that US bank account was where things got very interesting (and also was the best use case I've seen for cryptocurrency, where someone in BsAs would take your cash, buy local Bitcoin with it, send the Bitcoin to their partner in Miami, who would change it to USD and deposit it in your bank account there). It was a clever economy.
