Ideally, legal and biological fatherhood should be one and the same. That way you can find your genetic history for medical purposes and legal family tree for historical purposes. But tragically, in a few cases, legal and biological fathers are not the same.
This is of course a value judgement. I'm sure many adoptees would disagree with your assessment that their situation is tragic.
It's a biological and common sense judgment.

Ideally ( all things being equal ), adoptees would want to be with their "ideal" biological parents. Of course if the biological parents are dead, abusive or too poor to provide for them ( tragic ), then adoption is better than nothing. But I can't think of any child who wouldn't want to be with their biological parents all things being equal.
I mean, I could similarly assume the ideal to be mass incubation in artificial wombs, followed by randomly selected adoption.
