I buy this.
Daniel Suarez had a very similar idea, although he referred to it as the bot problem[0]. I believe this approach of identities withstanding "the test of time" solves the oracle problem but at the cost of a delayed solution. Initially you have lots and lots of bots and Sybil attacks are common. Then after a while, identities/nyms that exist and interact with the world increase in trustworthiness. Trustworthy identities will eventually be stolen or sold to bad actors, but like fake identities today they will be expensive.
My identity on hackernews is over 11 years old. Creating such an identity with the comment history, connection to a true name, and content over 11 years would be very expensive. Likely more expensive that a fake passport.
For instance Islamic State terrorists were buying counterfeit passports allowing them to enter the EU for 15,000 USD [1].
The major downside of such a system is that isolated people or people with few resources would be at a major disadvantage and we would essentially be replicating much of inequality of the credit score system.

In at least 10 cases the Guardian is aware of, people who illegally crossed the Syrian border into Turkey have used his products to depart through Istanbul airport.", https://www.theguardian.com/world/2022/jan/31/revealed-how-f...
