Honestly, this question reminds me of the Chinese governments mentality in regards to only having one child.
Holding to a moral view is not synonymous with China's policy of restricting couples to having one child - which BTW, has absolutely nothing whatsoever to do with morality, but with practical population concerns.
As I see it - and really as most people see it (even if they don't consciously acknowledge it) - this would be an immoral act simply because what you're creating for the child is a situation and circumstance in which most people wouldn't want to be in.
Do you value the relationship you have with you parents? Do you value the relationship you have with your grandparents? Do you love that three generations interact, yourself with your parents and grandparents, and observing that special connection that binds all three together? This is surely a richer experience than having been deprived of it.
This morality is essentially bundled up with that traditional experiential knowledge. If you don't find anything of special value in knowing and having a relationship with the people responsible for bringing you into the world, and with the people who brought them into the world - and if you don't appreciate the spiritual closeness of this relationship, than of course you would not see a problem with having kids at 65 or later despite the fact that you would be leaving your child bereft of a father after they reached a still tender age in life.
Ultimately, I'm saying this should be something closely considered before deciding to bring a human being into the world.
In any case, I'm curious as to how one could possibly think not having a relationship with one's father beyond 25 wouldn't be an issue for people. It would be a loss. And comparatively so; most people have that connection. Most people have living parents well into their 40's, and some even have grandparents at that age. Just thinking about this show, it occurred to me that my own Grandmother - who is 81, who I thank my lucky stars to have known for 27 years of my life, is still 13 years younger than my father would be if he decided on having me at 65. Think about that.
And again, I feel the need to reiterate the spiritual significance of seeing your parents present during the birth and rearing of your own children. This is something incredibly special. I still have not experienced this, but I can see and I realize just by observing other's how precious this experience is.
