Maybe not exactly the same as China's, but the "common understanding" that your internet persona must be tied to your identity, and that this identity can be scored based on a bunch of criteria. - or that how you spend your money must be trackable and traceable.
It will begin to grow out of the places that are already used this way: things like insurances, then will grow towards "securities" such as mortgages ("where do you spend money, does it look suspicious to us?"), and afterwards to "luxuries" such as air travel. Eventually nearly everything will require submission of financial documents and social profiles for nearly everything and only when that's the case: with a whole host of people wasting time on re-validation of the same information and a huge bureaucratic mess; will someone come along and give it a government sponsored name and a centralised point of access and scoring. - and it will be sold as being better than what came before, and it will be.
This is how other forms of centralised identification have grown over time, so I'm not pretending to have prescient knowledge of the future.
