It is great to know that the court (at least one of them) accepted the income of a spouse as evidence of a legal means of living.
It actually means that you don't have to show that you can support yourself if you can show that you are being supported by your spouse.
If what I have read in other posts is correct, Argentine taxes on foreign income are non-existent on Argentine citizens if they stay out of the counrty for more than six months of the year.
Not everyone who applies for Argentine citizenship has a desire to live here. Some just want a second passport and some of them will "game the system" by getting temporary residency which does not require them to pay taxes on their foreign income while they are satisfying the two year residency requirement for citizenship.
I am not being critical of anyone who does this. In fact, I think it is a "brilliant" strategy.
