I think this is a very pertinent point for Steemit. There are a large number of people who are "idealists" on here, myself included and particularly at least one of the founders. This describes the current demographic but will not play to a wider more mainstream demographic. I think "Libertarianism" is currently the most popular idea around these parts, but this will change. If allowed to grow organically I believe the end result would be more akin to a Liberal Democratic Republic online with its own currency and eco-system. If you take this "experiment" to it's logical conclusion, then I think this could eventually drain all the value of all fiat currency into this eco=system, replacing all fiat with Steem. Once this happens, we will actually have a functioning global currency, equitable and transparent to all complete with economy and global de-centralised consensus and governance. The world's citizens could truly govern themselves much more directly than current representative Democracy.........perhaps?
