When I was reading the whitepaper this is one of the first things I thought of.  If people have no access to banks then getting cryptocurrency isn't always easy.  There are places like Wall of Coins where you can go to a Western Union type money service center and deposit fiat to a specified bank account and receive your coins that way, but people in 3rd world countries aren't likely to do that.

I got the impression that WeTrust will primarily be used in smaller financial markets in already developed areas and as a "fun" way to save among a group of friends.  We are still very early and who knows how widespread and easy all of this stuff will become.  We're only a year into this whole cryptocurrency popularity boom and the sky, or moon if you will, is within the realm of possibility for many of these coins with good ideas behind them!
