I don't think you can let people die if they have the money to pay for the treatment. How would this even work in a capitalistic society ?
Also the real goal of medicine is not to let people live aslong as possible but to let them live long while staying fit and productive. It is theoretically possible to refresh all the cells in a human and repair the DNA. We are not there yet but staying biologically young while being 80 or 100 is not impossible.
