actually it is a wrong statement about "Have No Access to Banks" because I find this impossible because all of us can access banks unless we deny using them and that is what the truth here.
those people who don't wanna use banks and don't wanna be interfere of 3rd parties and government are those people that wants and love using bitcoin and yes I am one of those like yours guys.
I think it is basically about the fact that world is not just our nations and there could be some poor nations with very poor towns and even poorer villages, which means that those people may not have access to any ATM or any type of bank. I am not saying this is common, it is very rare, and to be honest bitcoin wouldn't really change much for those people unless it's all adopted by everyone in that village, which doesn't really exists right now.
But, it is definitely a good thing for poorer nation citizens to work for richer nation citizens and make a good profit. As I always say, 500 dollars may not be a lot for American coder, but could be a great amount for me.
