"will be useful" - why ?  Why is this useful at all ?

Here is a good article on the possibilities:

In some areas the blockchain may even make life easier for governments. Last year Dubai announced that it wants all government documents secured on a blockchain by 2020, a prerequisite for agencies to become completely paperless. The technology could also be used as a cheap platform to generate what poor countries lack most: more efficient government and trust in contracts. And some hope that the blockchain could make the United Nations work better by helping it keep track of all its programmes, creating transparency and reducing waste.

The possibilities are endless but not in their current form.
