Licence (license) to procreate ?

I would never support such a thing, but I suspect that at some point, there will have to be a maximum legally allowed number of children and some sort of penalty for violating it. If the population keeps increasing, sooner or later, there will be widespread famine.

There is already in China, with taxation as the sanction rather than litigation.

I believe a population-control dept should be set up by govts that only allow licensed persons to procreate, depending on financial supportability, ethical intellect and social standing.
Also, the right to extinguish life upon request of recipient

Those who procreate, unlicensed, should not be discriminated against or penalised, other than prevented from receiving state assistance or welfare benefit.

This policy is being phased out. The Chinese government is concerned about negative consequences such as the lack of adult children providing care for aging parents.
