Im not really sure about what you expect off the Argentina's defautl thing. People is poor and can barely go from month to month, they don't give a shit about Bitcoin, they just want the basic needs, that you need first covered to even consider giving a shit about Bitcoin.
The people that would benefit from Bitcoin is the small amount of people that have any relevant amount of money that they want to hide in Bitcoin before they steal all of their shit.
Do you mean a need like the ability to store value without having your purchasing power eroded by hyperinflation. Because that's exactly why nobody can get ahead. Fiat gives government the power to rob the populace to pay for their mistakes. Bitcoin takes this power away.
