Does Argentina accept US dollars?

Could you elaborate on the current status of Argentina's acceptance of US dollars? I'm particularly interested in whether there are any official policies or regulations in place that dictate whether the country officially recognizes the US dollar as a legal tender. Additionally, I'd like to know if there are any restrictions or limitations on the use of US dollars in Argentina, such as for making purchases, paying taxes, or conducting business transactions. Finally, I'm curious about the practicality of using US dollars in Argentina and if there are any popular ways that individuals and businesses alike typically use them within the country.
