Well hunting is a pain in the ass as it is. In an industrialized society we traded markets with shared goods to more specific specialties. Sure I can hunt for food because of licenses and availability but the trade off is most of the people have really good health care. At least objectively they have access to healthcare that can cure things that back in the 1500s would kill you within days.

My point is that at some point someone said "Hey I can take care of the meat portion if you take care of (insert many specialists careers)." There was no morality involved. Choosing to be vegan is fine. I think that it's easier to get certain things from animal sources. So does nature.
