Bitcoin could be useful in allowing direct transfers from user to user but for such a feature to be utilized there would need to be basic infrastructure like electricity and internet. If third world countries start having those then there could be a leapfrog to bitcoin.
True, additionally bitcoin can be an alternative job for those who have not found stable job here and as well it can provide people in a community a money to pay for their expenditures online. I think also bitcoin may help community if it can contribute some of its profit to provide better establishments, public services and local entities which will help people to live peacefully and contented , but then If it will not happen government may still acquire tax from bitcoin to used for public services.
