Interesting idea, thanks.
My original comment was more around ensuring that customers are protected from bankruptcies and other situations that severely impact them like these neurological implants. I'm not saying we should've prevented the company from selling these things. From what I've read, it's incredible what was possible and how the lives of these people were positively impacted.
I was thinking more along the lines of something like the Superfund program or how nuclear power plants are legally obligated to set aside money for future decommissioning. Maybe some form of legally mandated insurance program. Or regulating support time frames or mandating how long replacement parts must be available or remain in production.
