Taking the rationing argument to the extreme, suppose we could take a painless treatment once a year that would stop all aging and disease but costs $1 million. Would we still innovate in cheaper, less effective methods? We couldn't possibly pay for the treatments for everyone, but should they be subsidized for some? Would there be pressure to make the treatments illegal for those who can afford them? What if for a quarter of the price you get half the effects, but you can still only take it once a year. What would be the optimal time to not age/be disease free a month, a week, a day?
