It is all about Justin Sun's ego. Above all, he wants to show the whole world that Justin Sun won the war against the steem community. In the worst-case scenario, even it means losing the few millions he used to buy seemit, even it means owning the ghost steem blockchain.

But he is relying on something he understands and believes - money and greed. He believes once he takes controls of the chain he can win back the community by offering them money and additional financial benefits and appealing to the greed of the community.

I believe this is what he will do once he takes full control of the chain.
