Wow, what a fascinating post and equally fascinating comments.
My reading of this is that it all boils down to how you incentivise people to power up the vote rewards that they receive - because it all starts to feel rather futile if vote rewards dished out by us mere mortal minnows / dolphins (the 1%,that needn't be that high as per the post) are routinely cashed out (let's exclude here cashing out for genuine unexpected life expenses; what I'm talking about is more frivolous expenditure like new cell phones as someone else mentioned here).
This then means that way fewer than necessary progress up the chain as is needed for this platform to work.
