Until WWII it was normal to loose your citizenship when you apply for a second one.
That´s why the AR National Constitutions establishes low requirements for citizenship and that foreigners cannot be forced to get AR citizenship. That´s why in Argentina residency is an option to citizenship and not a previous step.
During WWII, Hitler cancel the citizenship of all the Jews creating the category of stateless. Loosing citizenship, they became people without rights and that´s how legally he slaved them and killed them.
That´s why the
Universal Declaration of Human Rights enacted just after the WWII established that citizenship is a right. It means that it cannot be taken away and the whole human right philosophy is about that you have rights because you are a human being instead because you are a citizen.
In this point, the Argentine National Constitution was almost a hundred years advanced to its time. Among other things because art. 20 and 14 recognize same civil rights to foreigners and citizens with the only requirement of having his home in Argentine soil.
You know that even nowadays in the US you have limited civil rights or none when you are not a citizen.
Universal Declaration of Human Rights
Article 15.
- (1) Everyone has the right to a nationality.
- (2) No one shall be arbitrarily deprived of his nationality nor denied the right to change his nationality.
The fact is nowadays
citizenship is considered to be indispensable. This is Ius Cogens, it means, mandatory international common law. Even some countries still doesn´t accept it, it is only a matter of time to achieve a change.
But there is not a right to renounce your citizenship.

Just a few countries takes your citizenship away if you get a new one. None of them are/were precisely a land of freedom.
Former 3rd Reich (Germany), China, North Korea and Japan. All those counties has a bad record in their history regarding the lack of respect of human righs and freedom.
Germany has an special Court for applying for a permission for dual citizenship, however, the citizenship law of Germany is still too nazi.
China and North Korea need no further explanation.
Japan has its own nazionalism.
So, it is not bad that your homeland doesn´t allow you to quit your citizenship and I believe that it is regarding improper legal advice to try to resign the citizenship to avoid pay taxes. I think that the strategy should be different because dual taxation is confiscatory and using this argument it should be easier to win the case.
