Childfree absolutely isn't a choice for everyone. The idea that we should punish those who are too unattractive, disfigured, or disabled to attact potential mates, or those with medical conditions preventing them from having offspring, or those with highly heritable diseases that would negatively impact the quality of life of their offspring, is as inhumane and cruel of an idea as I could think of. There is no justification for punishing those who already have a hard enough life as-is, give them a break FFS!
