The government puts new restrictions and then people find away around them. It generates a lot of work for the bureaucrats and a lot of inconvenience for the people.
But a large segment of the Argentine population is convinced that Argentina has its own law of economics and that just letting the market work things out, may work in different countries, but not in Argentina - maybe its the magnetic pull of being close to the South Pole. What did Einstein say about trying the same thing over and over again and expecting different results.
Having said that, Argentina is only different in degree - not is substance. All the so called advanced economies are resorting to QE and other tricks to try and goose the economy. QE is just a sophisticated trick that the average Joe doesn't understand, but it is ultimately as idiotic as any of the other pathetic fiscal tricks most governments are resorting to now.
And like all these tricks, the rich and well connected find a way around them. The poor and middle class get slammed.
The rich in Argentina already have overseas bank accounts that they can draw funds from. In the US, the rich are the only ones that have benefited from QE as asset prices rise.
What particularly galling about these tricks is that so-called liberal economists like Krugman say that QE and "stimulus" benefit the poor when the result has been decades of increased wealth concentration in the top one percent. I would be willing to bet that in Argentina as well that wealth has become more concentrated at the top since the currency restrictions have been in effect.
