Most (or almost all) businesses are built with "a moat" to help them protect their competitive advantage, and secretly dream of becoming monopolists and extracting the ensuing rent. Against this background, blockchains appear horribly disruptive, as they expose rents being extracted by incumbents.

How about investing unlimited amount on Steem, is this not a monopoly?
Maybe we could minimize or say put some tolerance on investments, a limit on amount to invest on Steem in order in some way to reduce the gap or make some a little bit of balance on the investments between the few huge amount investors and the many little investors.
My words are quite rambling, I hope you understand what I mean.
