You clearly have an attitude that is very hostile to the idea of using technology in any kind of “non-technical” area of human affairs, and appear to believe the only possible impact this may have is a detrimental one. I have acquired The Circle novel which you reference, and though I totally agree that such a surveillance-centered business would be a dystopian nightmare, what you seem not to realize is that of all the technologies that have been invented, decentralized and/or block chain based systems are the *first* invention that gives us a fighting chance to successfully prevent such a system/company/model from arising. If a situation like the one in The Circle is something you don’t want, you ought to be totally in love with decentralization and a user-centric economy.

What is interesting is that a major problem with current societies is not too much capitalism, but too little. Intermediaries have an interest in stopping any kind of innovation that would make them earn less, become obsolete or god forbid irrelevant. They only like capitalism as an excuse for pursuing profit at any cost; not if it actually would do what it is supposed to, which is to make markets more and more efficient, in the process inevitably decreasing their role or eliminating the inefficiency that they would eventually become altogether.

If you look at where the most “unfairly accrued” wealth and influence is concentrated, it’s exactly at those intermediaries… brokers, banks, property managers, and so on… decentralized transaction systems will soon relegate these greedy bastards to the dustbin of history.
