That's great! People should be in touch with the foods that they eat, preferably ones that they raise and aren't kept in nightmarish conditions on factory farms.
If people in my completely made up fantasy world eat tons of meat then that's fine too, but I do have a suspicion that many people wouldn't be so fine with doing it. I personally could not, so I don't eat animals.
That's not a solution.
My grandmother's generation (, Chinese) has extensive experience with slaughtering animals. That generation still likes and craves meat.
You might have people who chicken out in the short term, but in a couple of years getting a butcher license will become normalized and you're back at square 1.
