Why do we insist on growing meat in the lab, when it already grows on animal in a natural way?

It could be seen as a naïve question however I think it's a part of bigger trend where humans are trying to replace natural processes with cultural. Isn't the science-fiction dream to grow babies in an artificial womb and give them to parents "when they are ready".

This trend worries me. I think we should go the other way and acknowledge and accept that we are animals and part of the animal kingdom in every way.
