According to President Fernandez, buying dollars is not a human right and it's about time people realised this, according to him. He also thinks it's about time people started respecting the local currency (peso) by saving them, so he doesn't want people saving in dollars any more. He's worried that Argentines have a dual currency mindset and are obsessed with it.
Quite how he's going to solve that Gordian Knot is beyond me, since he's already started behaving like Robin Hood and ignoring the fact that, no matter how hard they try, successive governments have condemned the peso to the lavatory with every moved they made.
Buying foreign currency may not be a human right - in fact it's not a human right anywhere - but in most normal countries, it is at least a democratic right, no more and no less than buying a coffee.
