The example was already given, biometric monitoring could be used to help elderly people who want to maintain their freedom instead of being shoe-horned into a home but it could also be used to decrease staffing costs as well if it can be done in a non-invasive (in the medical sense) fashion. I'm not sure what your grudge against the elderly is or why it's hard to comprehend that as people age their medical needs increase but nothing about this is news to people who work in a field that services older demographics. This whole line of dialogue is a red herring though because, regardless of if you agree or not, the point was that this sort of technology has real use cases that are driven by consumer demand. You can romanticize these experiences all you want but the reason that tech like this finds consumers is because it's meeting real needs. This idea that the populace at large is only okay with data collection because they don't understand it is just a way for privacy advocates to sidestep responsibility for any useful tech that their policies might render impossible.
