It will be hard for who to have power in the Chinese market?

For Steem to have power in the Chinese market?

I think the government would be less interested in regulating Steem than they would be interested in regulating the content that would be shared on a Steemit mirror.

They could end up banning Steemit and all related mirrors, and just have a region-locked Chinese Steemit all in Chinese and made ''party-friendly'' for mainland Chinese users...

Users in HK and ROC could still use the regular Steemit (for the foreseeable future).
Chinese users with a VPN connection could also use regular Steemit.

Basically we'd be offering the Chinese market a seriously nerfed/regulated version of Steemit to be used exclusively in PRC (Mainland China). It wouldn't really affect Steemit, but it would definitely affect the price of Steem and the Steem blockchain. Drastically so.

Does that clarify anything?
I'm not sure I really understand what your point was about having power
