As I understand it, this procedure would result in a near perfect clone baring a few random mutations in the stem cell which they could probably screen for.

To digress. I want a clone, more than anything. It's only thing I'd pay more than $100k+ for aside from housing.

I submit that society would benefit if every other generation was a clone. If I were raised by my parent-clone I would have matured faster and been more skilled at playing baby-roulette with a natural child.

Whenever I meet a 20-30 year old that has the temperament and calmness of a 40-50 year old I suspect one of two things:

1) their young-ish parents won at baby-roulette and their child had a personality similar to theirs and were able to guide them through adolescence in a more optimal way.

2) their parents were older and maturer and could navigate the personality conflicts in a way that didn't lead to long-term family dysfunction.

but even #2 is rare since not all older parents can handle all personality types, hence my suggestion for a third option: family lines based on alternate generation cloning.
