I myself am nonvaxxed against covid, so I understand and respect your stance. I agree that the STF obviously has too much power, although I am very unaware of the intricacies of the situation in Brasil so I can't comment on the concentration camps allegation...
There are some laws that exist on paper in Argentina but are completely unenforced, and even if they are enforced, it is easy to bypass and ignore them, so I doubt anyone will have to pack their bags in response. Also, important: article 13 of law 27491 essentially makes the whole thing moot...
It says:
The law 27491 was regulated by decree 439/2023.
It says:
So, the whole thing with regards to issuance of documents seems to be made irrelevant by these lines, but of course, the law still exists and could probably be enforced selectively. The law does contain a provision for forced vaccinations (article 14), which is very problematic. And of course, the law also required the government to create a digital database of the vaccines that people have, just one more piece of data they have on everyone.
One more piece of data that anyone can hack into and sell on forums which don't look too different from this one...
Anyway...
All large countries, such as Brasil (and the US, and China, and more), tend towards authoritarian policies to control their large populations - one example, is the conscription in Brasil, in addition to the vaccine laws. Only a very small percent of the pop. is actually conscripted into service, but all men unfortunately still have to register and get the military enlistment certificate, which is required to apply for a passport there (they do enforce this) and to carry out many other life functions.
I'm not aware of any anti-homeschooling laws or forced vaccinations in schools there (I don't keep up with the news there), but if forced vaccinations without parental and individual consent are indeed happening, it would just be a continuation of the authoritarianism that is deeply embedded in Brasilian society. So, I really do understand why you're selling your property there. The best solution in the case of authoritarian governments is to leave. Argentina is much nicer with regards to freedoms, especially freedom from authoritarianism.
Milei will fail.
