There are a lot of benefits from the blockchain but there is one that is probably more powerful than any other and I had not see a much interest on it. That is the correlation between consensus algorithms and forms of government.
Finding the best form of government has been one of the biggest problems in human history. There are too many factors that don't let an answer to be found, for example, poorly educated nations, conflict in interest, been ahead of its time ...etc.
In my point of view, consensus algorithms such as PoW, DPoS, tangle... and many others (whatever electroneum will use), are less susceptible to manipulation than forms of government because the power of a cryptocurrency relays on the trust of people, so if you don't like a cryptocurrency you can simply stop using it, but if you don't like your government is much harder to switch to another.
Also, the world of blockchain and cryptocurrencies is changing at an enormous velocity in contrast to the almost static world of forms of government.
I believe that in some years we will find something better than our current system, maybe direct democracy (PoW), maybe delegated (DPoS) or maybe something totally different.
