That being said, it also seems to me that the vast majority of people’s diets are not well optimized for health. Most people care about convenience, cost, taste, and other factors as well. My intuition is that if we took a random person and said “hey, you have to go vegan, lets try to find a vegan diet that’s healthier than your current diet” that we’d succeed the vast majority of the time simply because most people don’t eat very healthily. That said, the random person would probably prefer a vegan diet optimized for things other than just health more than a vegan diet optimized for just health.
