If we are talking about a Total Decentralized Country without government then I for one highly think that this is just realistically totally impossible.
A country like that would mean all decision making and planning are distributed to all people in that country. If the country has a population of 100 Million, then that would equate to 100Million deferring ideas, opinions and thoughts most of which do not have the knowledge nor the experience to make an informed decision. A country with that size would definitely take a lot of time to tally everyone's votes.
That is why there is "Government", to make all things organized. People choose their representatives and that representative will make the decision for them. If you look closely at Steem (a blockchain and platform that claims to be decentralized), our government is like our "Witnesses". We vote for them and they make all the decisions for us. Which is a solid proof why countries need representatives and/or government. To reach a consensus and decisions fast.
