It makes sense. I imagine first and foremost everyone wants to make money on their investment. I do know he actually bought some of the tech, but the majority of Steem is still free to use and fork or whatever. But I can't even see a fork as a viable option unless he does something really messed up. Too many people would side with him if some decided to fork him out just because Tron and Justin make them sad.
I do think your idea is worth considering in the next hard fork after SMT, especially if the power down time is going to be reduced further. Another idea is to have STEEMIT accounts use the novote feature which would mean they would have to go through a power-down cycle (power down then power up) to cancel that giving everyone enough time to react.
