In general, a commitment means little if there’s no punishment for failing to follow through. If a platform can’t impute a punishment on those who fail to follow through, it is not particularly good, maybe not even the thing we’re talking about.
Regarding sybil attacks, in New Zealand, there’s a state-funded auth system called RealMe that ensures one account per person. You use it for filing taxes. I’ve seen non-government services (crypto trading platforms) that use it, as any other site would use facebook or google auth (it’s also conceivable that facebook might provide fairly reliable real identity verification one day).
So many online systems need something like this.
In conclusion: Very simple state functions (violence-backed contract enforcement. A real identity auth system) can change the possibility space a lot
