I think apps that want assurance of your identity should pay for your kya. They want valuable people after all, and this should go into their CAC. Users still pay nothing, the identity service does not care about their info, after verification, it drops any details, like uploaded documents, whatever, keeps a certificate.

The cost for this service is likely keeping up with ID systems for multiple countries, infra and support.

Potentially, if this is made into a protocol, it can be decentralized kind of like the SSL system, so each country manages it's own rules.
