OTOH, it's interesting that you and the parent comment are basically saying "We, as a country, are failing our pensioners so badly that death has become the more appealing option for many of them. Therefore, we must trap them here with us until we improve the conditions that lead to them making that bargain (which we will never do)"
Taking away someone's right to assisted dying because you live in a society that has made death preferable to living for many seems like a totally orthogonal leap of logic. That doesn't reduce net suffering one iota.
