While the core idea has some merit, the People's Republic of China uses this as a tool to bash Taiwan with. Overall I'm not a huge fan. It can be used to describe large states that control entire specific civilizations but most states, Turkey for example, are undeserving of the term.
I don't think the arguments that the PRC uses against the ROC is relevant at all to the validity of how you could describe the relationship between the Chinese state and people is vis a vis other countries. Neither here nor there.
