Well, this would be a bad time for Whatsapp to cut off service in Argentina, the blowback would be impressive, and now there are equally good message services out there like Signal and Telegram. I would expect a lot of people have all 3 apps installed on their mobiles. I imagine it would take less than a week to duplicate Argentinian government Whatsapps to Signal or Telegram.
It's different to cutting Oz off from Facebook, there isn't any real alternative to FB yet, unfortunately, though it does at least seem to be becoming obsolete anyway.
I did think that Whatsapp backed down in Europe over the changes (due to the EU's GDPR data privacy regulations), and that they wouldn't take any action against users in other parts of the world for not accepting the new terms and conditions. Since we're mostly expats here, it shouldn't be too difficult to have a friend or family in Europe by a pre-paid SIM, have them activate it, and have it receive any activation code from Whatsapp (or anything else you want) before having it put in a drawer. Activate the online account for the SIM and feed it small amounts of money every so often so the SIM doesn't get deactivated and the number recycled, I did that 2 weeks ago when I moved to a new phone, no Argie Whatsapp number for me, and I'm protected by GDPR
