There could be other scenarios as well - do remove the witness voting rights of the steemit account's but allow them to delegate to some account, that will rather use that power to prosper the blockchain. For example, their power can be delegated to lot of curation accounts. And in parallel, Justin put up a marketing plan ( which he is pretty good at), which will help steem's value go up. And then once we are at a sizable growth, percentage of his stake allowed to be withdrawn - which he can sell or do whatever.
A WIN - WIN for everyone.
I don't think that the witnesses will allow steemit to vote on witnesses. That is the whole point of this soft fork.
Yes, that is what I also meant, edited. Remove their witness voting, but allow their stake to be used for a better usage.
