True, but Bitcoin requires a cell phone or consistent internet access, doesn't it? And there's no recourse to having your money stolen or lost? I'm not sure those are appealing scenarios to the poor, either.
Transaction fees aren't high "just because". Otherwise anyone could open a lending facility of some sort and kill it. I mean, it's not like Western Union is making excessive profits. There's a matrix of risk involved with the movement of money. Bitcoin solves some, and creates others.
