How exactly did the argentinian government do all that? That inflation is high is a sure thing, Argentina never defaulted on its whole accumulated debt and the government is still having to devalue in order to reduce the remainder. There are only two ways of getting rid of unplayable debt: inflation or defaults. Pick your poison.
But what about trade? Is the argentinian current accounts flow balance positive or negative now? If negative, I can easily understand problems with imports, and I wouldn't be convinced that the government is to blame: keeping imports will depend on willingness of lender to borrow to a country which as not yet completely gotten rid of its debt problems, and the government will have a duty to prioritize essential imports (energy, machinery, other productive stuff) over tourism and other imports for consumption.
If they have a positive balance it becomes harder to explain: the only explanation I can think off is that such a government would be forcing the build-up of deposits in banks at home, in order to use that money, probably as a cheaper source of refinancing for outstanding government debt being rolled-over.
I do need to overthink before judging, if by overthinking you mean discussing the specifics of the argentinian situation, the constraints under which its government must operate. The same trade policies, tax policies etc, may be good or bad, depending on the present situation of a country.
Their debt is hardly unpayable by now, in fact their public debt to GDP ratio is rather low at 42.9% (in Brazil the public debt is 54.4% of GDP, and inflation is about 6%). They wouldn't need inflation if the government was to run a primary budget surplus, instead of running a primary deficit year after year. I don't see why Brazil, Uruguay, Chile, Peru and Colombia can run primary surpluses but not Argentina. So the issue here is not debt, but rather deficit (the primary deficit was of 2% of GDP in 2011). So they keep an extremely high inflation that royally screws over Argetinean workers who lack inflation-protected securities, and try to mask that by giving big nominal wage increases year after year which in effect are zero if not negative in real terms. And of course nothing justifies the fact that the Argentinean government has engaged for years now in blatantly falsifying inflation statistics, threatning with jail anyone who dares publish the real numbers.
As for trade, they actually have a sizeable surplus (they exported 84 billion dollars in 2011 and imported 72 billions). That they're still worried about stopping all imports is another sign of their gross mismanagement, since they need all the dollars they can get due to capital flight and the budget deficit.
As for books, they're about 0.1% of Argentina's imports on financial terms. The reason for banning foreign books was not economical, it was political (censorship). Any government that goes after books is automatically evil in my view.
