Really great post! Yes, Steemit is a microcopy of what the real world is. Nicely told... But your cap solution is not ok I guess. If the majority of voters wants to give someone an extra big welcome to the community or like their content so much, they are the owners of their Vote... Introducing a cap is a bit like expropiating them. If they want someone to be number one and they cherish his content so much that even if his content is worth 10.000 USD they still want him to get a bigger part of the pie than let them...

I think you did not mean it this way, but your measure in this regard reminds me of politics where they want to introduce how much a private corporation can pay their managing directors...
I think this is not the way to go...

SP holders are the people who are the owners of the platform. I think they should be allowed to do as they please with their holding. If not investors will look the other way and not buy SP.

Then you get a Falling Steem Price and less payouts... less interest in the platform and so on... a vicious circle.
