I have never criticized permatourists and said so in previous posts.
They're just lucky that Argentina is (arguably) the best (if not the only) country in the world who doesn't take their own laws regarding "tourist visas" seriously.
At some point (sooner or later) that is likely to change.
Even if you don't have a "valid" tourist visa, if you are in Argentina, the chances of being deported are almoat zero and even if there ever is a "crackdown" on perma-tourists, the chances of being able to stay are high while the chances of being able to leave and reenter may not be as good.
