I'm on board with you here, after all it's just a ChainID.(Do users even care what ChainID they run as long as their data is saved and currency is worth $?) I asked the same question you are asking now to many Steemians the 4-5 past weeks and i believe they (majority) are past ready to hardfork to protect #freedomtechnology .
By deploying now, we teach the communists how decentralized technology works, and if Justin Sun continues to Sybil attack (semi-democratic) systems trying to cheapen our technology and immutability "features" , pushing a lot of fud on our consensus mechanic's abilities, he will pay the ultimate price of owning a network that no one uses and no one gives a fuck about anymore.
The big decision
Option 1
Keep everyone's data in the chain, only remove justin's / steemit's stake
Option 2
Don't keep the social data, only airdrop steem to the users who hold steem today, start chain from scratch (without user data)
Arguments for each side
Swap Chainid without data
Not storing ALL Steem data will restructure the blockchain fairly and potentially keep it very decentralized because more nodes can be ran, more witnesses will be operating.
Swap Chainid with data
Keeping the data would be nice , because so many creators trusted Steem data, it's a root/tie to potentially 500,000-1 million actual people. Immutable data can create a platform enabling time - period immortality if the system carries on with adoption and keeps up with maintenance into the future
