I get the impression that every influential entity has plans of creating its own currency. There's even speculation of Facebook creating its own ICO.
Do you think that fractionalized ownership will be applied to everything? Are all assets going to be tradable?
It is a good idea but I think it will appear in a very distant future. Our world is still growing everyday but it is not so modern. What you say will definitely happen in the next 100 or 200 years. All countries will merge into one and technology will always be utilized.
