I'm not always in favor of what Christina does, but it is generally good to have a diversity of economic models active in the world, for the same reason biodiversity is important.
While most of the world struggled with the 2008 economic crisis - and Europe still struggles with it - Argentina shrugged it off.
Imagine if another longer lasting crisis occurs within the US hegemonic sphere. Countries like Argentina, which have one foot outside that sphere, will be able to survive and perhaps even lead growth elsewhere.
Life times of economic crises in Argentina have taught Argentines to depend on no one but themselves, which means protectionism sometimes.
