Bajo has his unorthodox methods. They may or they may not always work. The answers below are based on my experience:
1. You need 2 years of legal temporary or permanent residency. Not transitory/tourist visa. Before 2017 it might have worked trying out with just a tourist stamp/visa but the current regulations explicitly state that you can apply only with 2 years of temporary or permanent residency at the time of application.
2. Irrelevant. The judge may or may not ask Migraciones for your "movements" but as long as you were legally admitted and have spent more than 50% of those 2 years in Argentina it's fine.
3. Well duh.
4. Nope.
5. It's 30,000 ARS per month CURRENTLY at the time of application for the rentista visa/residency. That amount could change anytime.
6. Some judges might agree to take on your case with 1 year and 1 day in Argentina BUT most will just reject it.
My advice. If you really want to be an ARG citizen, get your papers in order, get a residency. 2 years after apply for the citizenship. It would take 12-24 months (18 average) after you start the process in court. So you are looking at 3-4 years total from getting the residency to citizenship.
Alternatively, you can hire a lawyer like Bajo and try your luck out without meeting all the requirements. But you'd be responsible to cover their fees and there are no guarantees your case will be accepted or approved.
