This is relevant when thinking about bringing the next few billion people online and into the global economy. These people will not have credit histories that are accessible to the same intermediaries that I am set up to use. They may have local intermediaries that they can use, or they may be willing to use Bitcoin directly. If that is the case, they will be able to enter into the stream of global commerce.
There are not right now many transactions between rich countries and the bottom couple billion people on Earth. Why is that? Is it because these people have nothing of value to sell or is it because we have no way of transacting with them? We are about to find out.
