About all this kid has as an advantage right now is a wealthy, famous dad, and maybe a chance at some creative music genes. Who knows if there will be any money for this kid later on, or if he blows right through it, or his mom does before he gets to it.
Father figures and other role models are fine, if you get a good one. But not having one can suck, being a single parent can suck (it certainly can't be easy - there's a whole forum here for single parents) and while people should expect their grandparents might die before they themselves are adults, people don't expect their parents to do so, or to be too old to take care of themselves before the child reaches legal age.
Just because some kids do fine without dad around does not sway my opinion on this. Money can't replace having a father in one's life.
Sure lots of kids lose their dads. But the odds of this child losing his father during childhood are far higher than most. All the money in the world won't replace him once he's gone.
So... the question then is, how many other people should not have children?
People who work in dangerous, potentially life-threatening occupations? Even if one parent doesn't?
Soldiers who might die overseas? Even if only one parent is in the armed forces?
People with a terminal illness, married to a healthy spouse who wants to have a child before they die? Should we refuse to freeze people's eggs and sperm before they undergo procedures (after all, cancers do return, and their predicted lifespan, even in remission, is still shorter than the average)?
Should any young person who marries a significantly older spouse, automatically give up on the idea of ever having a child of their own?
How about same sex couples who can't provide either a "mother" or a "father", depending on which sex they are?
Single women who find themselves pregnant and choose to carry to term, despite the father not being in the picture?
Single women who choose to have a child, by choice?
Is the only acceptable configuration for a family one young healthy mother, and one young healthy father, neither of which has any potentially life-limiting factors in their lives?
Where do we draw the line?
