My friend from Venezuela certainly would've benefited from owning a currency that wasn't regulated by his government, which made exchanging Bolivars for external currency illegal except for those with government connections.
Are you saying one should only be concerned about the state itself, that citizens ought to go down with the ship and be victims of the government they were born into?
I'm hoping you're simply ignorant of the very real personal problems of people born into corrupt and unfortunate countries have that are mitigated or solved by crypto currencies (even if it doesn't solve the problems of the state) rather than simply uncaring for their plight and unwilling to care about solitons for them that don't involve also fixing the entire corrupt nation they were born into.
