My input:
I have friends who live in Buenos Aires (CF) on about 2,500 ARP per month, so it definitely is possible albeit not very pretty and I do doubt any will stay on as-is for more than 2 years.
The biggest constraint for a foreigner wishing to make residence here is the housing situation as a local rent isn't normally accessible, but it is possible to arrange something without a guarantor by putting up the first six months of rent.
Besides the big vacation spots, my only experience of rural Argentina life is Cañuelas, a small country town 45 minutes south-west of Capital Federal, passing Ezeiza. I spend about 30 hours a week there and things seem cheaper, but to be honest there aren't many places available to rent, I hear locals complaining about it every once in a while (and not in the just-not-the-perfect-place sort of way, but in the actually-no-listings sort of way), as well as other towns around the outskirts of BA. I mention it as I've thought this might be similar in other areas...?
You can find an old, Point A to Point B car for a couple thousand dollars, probably less, if you decide you need one.
Besides that, if you really want to come here, you can probably make it work without making too many sacrifices, and if you can't, or you get tired of the place, you can just go to India. You can definitely make it work in India, and the weather is definitely warm (north: dry warm, south: wet warm).
