But with that rationale, so is our current factory farming process.

Animals don't naturally graze, they are fed all the food they need. They don't naturally die. They are killed. They aren't naturally conceived, they are inseminated.

Where does the "natural" absolutism end?

So instead of working on improving this process we are totally jumping ship to a artificial process? So basically we have given up on such a simple task of raising good cattle which our ancestors have been doing for centuries because some scientists found some cool trick to multiply cells in the lab and are looking for ways to push their cool inventions on the masses to feel good and important?
