Like I said in another comment, every single such vessel in existence (the container ship you linked and all the ice breakers) is owned and operated by the Russian government and operates in Russian-controlled waters (or has an escort). This is not a model that can be used for global shipping.
You have a point. Let's wait until China deploys their fleet. Going to be a long wait (15-20 years), but it is my strong belief that they will do it. I might be proven wrong, of course.
