All valid points here.What is even the benefit of declaring any form of residency in Argentina, over coming in and out as a tourist? What do you get with a DNI? The ability to open a bank account full of worthless pesos and attract the attention of AFIP? Buy a house you may never be able to sell again at inflated real estate prices because rich people in Argentina buy property instead of putting it in bank accounts? You can get health insurance via OSDE without a DNI. You don't need a car in Buenos Aires. If you have USD, it is far better to rent in pesos, rather than pay $300K USD to buy some ugly apartment in a rapidly aging building.
