I think you're a lot more worried than the average Steemian. A lot of us have already accepted that we'll have to fork away from Steemit (or let steemit fork away from the community), and the duplicated stake that steemit held can finally be used to fund the ecosystem. I get that this task is immensely difficult, but It's probably the only way Steem survives and lops off the cancer that is Justin Sun and Steemit Inc.
If a sister fork happened, the Steemit Inc stake wouldn't be used, it would result in the same situation we are in now.
I've already shared my thoughts elsewhere and believe the community needs to move past the stake and let it go, but it seems a lot people people are caught in a monkey trap and can't let go of the stake or find alternatives. If you say its not possible to repurpose the stake on a forked chain, oh well then i guess people will have no choice but to let it go.
You can repurpose it, but it would be counter productive. Only by eliminating it completely and using the SPS could we build something that will inspire investors.
