The problem is that the US has no proper/well working ID systems. A large amount of social security numbers had been compromised through leakage and are hardly reliably usable for identification anymore.

Through there are many countries in which this can be indeed done reliably sand effectively.

Through the main problem is still this networks are global, so bots will just register with origins where IDs can be easily faked/stolen etc.

But it might still help a lot for local discussions if you would make it clearly visible if a person had a no or a non local real person identification.

If such a system is done cleverly it could also help law enforcement while it still upholds privacy. Through it's will always be someway prone to abuse by police and similar if not done perfectly transparent but you can be sure that certain lobbies will invest insane amounts of money into making it non transparent over time. Which makes such systems potential dangerous to have.
