There's clear that almost all governments around the world are not doing too much good to their countries and that some of the inhabitants might have better ideas and law proposals to make a country "great again", but I believe it is pretty hard to "decentralize" the governance. Look at Steem: it is decentralized, but far from perfect. It is still in the hands of the human behavior and that changes according to life situations and positions.
I like where this is going.
EOS is decentralized as well, being another DPoS system. The governance there is not decentalized. It is a single contract that is signed by each individual.
Now, it can also be altered by any members of the community if one of the amendments is found to be bad.
Steem is decentralised but this is not the reason for its problems. The reason is the lack of competition. As soon as we see other alternatives that are open and censorship resistance steem will have to evolve or die.
