I agree with OP's point of view.
The government of El Salvador was quick to pass the bitcoin law as legal tender.
The population was not educated as OP says, planning would have to be done.
Now El Salvador has invested in some valuable assets ready to be used by Salvadorans and they are not used.
The opposition party to the Nayib government also does its bit by boycotting with marches and protests against bitcoin.
According to statistics, remittances continue to be received by the usual means in the nation of El Salvador.
I think that the government of El Salvador will be creating new strategies so that the population knows with certainty the benefits that bitcoin can offer them.
