I actually hate how distanced we are from meat in general, and agree that in general people should have the opportunity to kill their own meat.
That said, here's a real counterpoint. PTSD. I know people with severe PTSD from witnessing some unspeakable brutality like the violent death of a loved one or friend. Nobody should ever ask a PTSD patient to kill an animal themselves. Which is the problem with the whole "have to kill animals" thing entirely. Too many people have some traumatic event.
Honestly, I think that's where a lot of vegans come from. I have an extended family member who snapped after watching one of those vegan documentaries. She was weird before then for reasons none of us really knew, but she starved herself until she was hospitalized for malnutrition and her hair started falling out. When she got out, she wouldn't eat meat anymore and wouldn't talk about it. She isn't a "vegetarian" in any good meaning of the word, constantly struggling with nutritional issues and avoiding meat entirely because she can't bring herself to eat it. It has become a quiet ethical thing to her, but it's more than that.
So IMO, we gotta cure PTSD before making people kill. I DO think we should offer "kill and butcher your own meat" as an elective field trip in school. I got to visit my first farm in middle-school and it really helped give me a balanced view of the world of food. Even if it was just a chicken, if I could've killed my own, cleaned it, and cooked it, it would've really rounded out my head on the topic back then.
