Hoi, More relevantly it uses a fraction of the costs. Given that we grow exponentially and given that we do not have a healthy balance sheet, this is extremely relevant. When the nodes that serve user requests are close to the user, it will also mean that the Internet as a whole will have less traffic. This is particularly relevant in countries where access to the International backbone is a limiting factor.
With a decentralised infrastructure it is a sound strategy to have trusted nodes in many countries. This will alleviate the problem even more.
