Plural Passports without literally plural passports?

The fundamental choice is: if I have stamps from all of {PoH, Worldcoin, Idena, Bright ID, KYC, Web2}, what is the incentive for me to put all of these on the same passport, versus creating multiple passports?

One of the reasons I liked the idea of using a PersonhoodScore in this post was that it allows the system to scale against different sophistication levels of attackers, including handling dual passports elegantly.

assuming cost of forgery = personhood score, if the cost of forgery of identity 1 is $10, and the cost of forgery for identity 2 is $100, then the combined identity for these two is $110.

if you can get $10 in matching from identity 1 and $100 in matching from identity 2, or if you combined the passports + get $110 in matching, then there is no incentive to sybil attack the system.

If there is some partition of my set of credentials such that sum(payoff(credentials_i)) > payoff(credentials), then it is in my self-interest to maintain multiple passports along this partition.

I think this is what you already said in different words tho
