Hmm let me try to explain how blockchain is connected to all of this. On the internet you can find the like-minded community (be it game, chat room, etc.), but every single entity is ruled by someone with supreme power. Blockchain solves this by decentralizing the power. All of the subjects join the platform willingly, thus accepting the rules enforced by the algorithm. No person can twist the rules to his need just like that - there are simply rules that are "carved to stone" and are not changeable. When you find the like-minded community (such as Steemit), the more work you do for it the bigger say you have. There are means how to use the blockchain (in other words "permanently updated database of who has what) in real world. For example "Parallel Polis" in our country is an institute that runs completely on cryptocurrency, thus avoiding the need to pay anything to the state. They have basically became the state in the state if you know what I mean. Because of the Blockchain they have been able to emancipate themselves. There is of course much more to that, I tried to keep it as simple as possible so you could grasp it a bit more:)
