Yes in your case, the bank here in Argentina will have no concern allowing you to open a dollar account and to receive regular transfers. As you have read the fees the banks charge is low or nothing. The fees based on a percentage of your transfer amount have disappeared. You will need to do an outgoing SWIFT wire transfer from your USA bank, some charge $0-25 for each transfer, so shop around to find a new US bank with best international wires cost. Then the Argentina bank might give you their intermediary bank details, which also might have $0-25 transfer fee, though they might not be able to tell you.
Finally when you have USD in your local bank, you can use their feature to sell USD (sometimes labeled sell MEP Dollars) in the app or home banking to get your daily or weekly pesos as you need them at the most current rate.
Talk to the Comercio Exterior desk at your bank. Switch to another if there are fees. Each might have different fees depending on if source is Savings or other self-employment. There is at least two other recent threads here in the forums with more information than I can explain.
