I don't know the story well enough. I think its probably good to first acknowledge that this is like, the edge case of all edge cases; I think it posses a systemic risk to enact any kind of rule or policy based on edge cases; this one was brought up against the unvaccinated for example, a naked swing at justifying the depersoning of tens of millions of people. There's a values issue here, it looks like she was ostracized by society and health regulators mistreated her, I would hope that today a humanitarian group would do a better job of meeting her needs. I would also hope that today technology has helped us grow past some of the complexities of the human condition; there is little point in having an abortion if a baby could just be safely delivered prematurely and adopted out for instance; today Mary may have found a similarly fulfilling and self sufficient life in cooking for herself and streaming it on the internet, as well as medical advancements in prevention/treatment/cure of dangerous diseases.
No answers to how you fix it, you asked for our thoughts and that's all I've got for today.
