You might want to check LocalBitcoin's usage in Venezuela [1] to get a clearer picture. It's not pure propaganda.
The use case in Venezuela is wealthy Venezuelans getting their wealth out of the country.
When bitcoiners say "refugees" as a use case, they mean rich people looting and running.
I'd say if you have enough money to be a capital flight risk, there are far less cumbersome means to get your money out of the country than crypto.
