> In 200 years, suppose there is some crisis we cannot predict and the recital is to be interrupted or stopped. There will be an incredible amount of pressure on somebody to make a good choice. Pressure that was created by a distant ancestor, of sorts. That might be part of the beauty of it, that might be part of the bond that ties different people together throughout time and it might be wonderful. What if there is a caretaker that is ready to retire and cannot find the next caretaker? That seems like a horrible position to be in.

We have plenty of examples where this has already happened. Traditions that were maintained at significant cost in the face of difficulties or opposition. Caretakers of something ancient who struggle to find an heir. We tend to view them positively.

> Japan is or was doing multi-generational mortgages a while back (I assume they might still be.) as it was the only way a family could afford to buy a property.

I suspect this has been misreported. Japanese mortgage terms are pretty normal and property prices are much lower than in the west (even the bubble only really affected central Tokyo). There's a practice of an elderly parent being able to get a mortgage that's then "inherited" by a child, in cases where the parent is retired or close to retirement, but it's pretty much a face-saving (and tax-avoidance) measure.
