It doesn't have to. None of that is an intrinsic property of animal husbandry. All of what I mentioned seems to be intrinsic to cultured/manufactured meat, though.
It is intrinsic to the animal production in the quantities we consume, though.
If we returned to 1950s levels of meat consumption (my parents and grandparents regarded eating a chicken as a treat), or grew chickens or cows in our own backyards, maybe. But in a world of 8 billion people with our diets, cruelty, pollution, carbon impact etc are all intrinsically tied to our meat consumption.
So lab-grown, cruelty-free, without the carbon impact especially for highly polluting animals like cattle -- it's a wonderful idea.
