With Apologies to Johnathan Swift
Importantly, personhood is not to be considered permanent. Persons may regress to BoC status at any time by becoming dependent on others for support, or by interfering with other's enjoyment of their lifestyle choices. In cases of person-to-BoC regression in which M- or FGUs are unavailable, the State in its wisdom may assume their role, acting (as the archaic Latin phrase puts it) "In loco parentis." * This would greatly reduce dependency and in fact create a new income source, as organs from aborted BoCs could be sold on the open market. The long-civilized and ethically advanced Chinese have instituted a similar system.
The social benefits of this simple change in philosophy would be immense. Not only would public expenditures and the jobless/homeless rate decline dramatically, but persons, freed from the life-sapping demands of BoCs, could actualize their true selves, whether in art, literature, music or late-night bacchanals at their favorite clubs. Crime would decline since imprisonment, a form of dependency caused by unpleasant interpersonal behavior, would create BoC status and engage "in loco parentis" abortion. All of this ethically advanced policy would certainly be easier to enact than reversing longstanding programs which subsidize lifelong dependence and the creation of future dependence, with little if any concept of social or moral obligation. The United States could then legitimately claim to have achieved the Great Society.
