I understand your sentiment but there's a reason people enjoy eating meat, it feels pleasureable in our mouth because it is rich in nutrients and rare in nature. In nature you don't eat meat every day like we do in our current society.
Just like donuts and candy tastes nice is because there's a lot of sugar and fat in them, things that are scarce in nature.

The point Wikipedia tries to make is clear.
What I'm trying to argue is that there are nutrients in meat that you are unable to get anywhere else than from meat. Yes, I fully realize that we can synthesize these things artificially but you still need them. As with most things in life, the optimum is somewhere in between. One could eat no meat at all, one end of the scale, one could eat only meat, the other end of the scale with the optimum probably somewhere in between.
