It's easy to live a long healthy life without ever eating meat, so, with a few exceptional cases, yeah it's completely a question of what you prefer to eat. A cow will live about 20 years on average. A dairy cow will live about 4. I'm having a hard time coming up with a definition of "natural" that fits the latter. And for most of human history it was a small fraction of animals in the wild that would up on a human's dinner table (American Buffalo, for example). It doesn't seem likely that humans are ever going to have to worry about predators again but meat production is a huge contributor to climate change so we are going to pay for our meat habit one way or the other.
