New born babies don’t happen every day, once a year is a good max per person (yes twins, triplets exist, but for simplicity sake). Maybe each person has a birth certification vouch once per year. Perhaps a lifetime maximum of birth certification vouches (3? 10?)
Moreover, children should not be coerced into participating in the registry and perhaps a perverse economic incentive exists by a malicious parent. Perhaps the child has a trusted guardian or adult in their life (teacher at school, church member, community leader, etc) who can vouch for the child.
the $ubi drip for children could be considered a type of child support, however the $vote token should be thought out more thoroughly
Further, perhaps, in order to receive $vote tokens, the child must obtain the vouches from a large number of people (10? 20?) which would be larger than anyone’s immediate family. This could be a competency litmus test of sorts. Otherwise there could be perverse incentives of malicious manipulatory parents / guardians taking advantage of children’s $ubi and $vote tokens without their consent.
