This logic (particularly the suggestion that someone having a financial interest is harmful) seems highly flawed to me. If someone buys into Steem, particularly in a big way, they are invested in the success of the system. The idea that people with an investment in the system would act to maintain and improve the system is very much built in to the design and discussed extensively in the white paper.
Why do you think this is a bad thing?
Slave owners had an investment in their slaves. They maintained and improved them to turn a profit. Nothing more, nothing less.
Today's monopolies utilize government to quash competition. There are no new ideas that can be fully developed. Anything that seems moderately successful is either destroyed or bought out by the monopolies within one or two years.
