Bitcoiners and anyone who doesn't live in Argentina (99.5% of the population) have the luxury of not taking this issue seriously. If it works out they benefit and if it doesn't work out it doesn't affect them. That's not a childlike illusion so much as a standard self-centered attitude.
To say that central banks do not extract value from the citizens that use their product is provably false. This is the entire business model of a central bank and cannot operate in any other way. To say that Bitcoin can't help citizens store their value outside the control-grid infrastructure would also not be a wise platform to stand on.
Unfortunately there is indeed a very high chance that this outcome fares poorly for the people of Argentina, which after all is the main topic of conversation.
