I've tried a lot of different fake meats, and real meat tasted better to me. Sure, meat requires special cooking to taste good. That doesn't mean meat as a whole tastes bad. When other things are cooked the same as meat, they don't taste as good to me as meat.

>Dogs also taste good but they are way less convenient to raise per kilogram of meat then cows.

I'm not saying that meat producers don't optimize their production to lower prices. I'm saying that despite their optimizations, vegetarian foods are cheaper to produce than meat.

>It's easier to keep some cows on grassy hill then kill them, than to create and maintain a field there.

Look at the price of beef vs the price of vegetarian foods. Beef costs more. Also look at the carbon footprint of beef vs vegetarian foods. Beef production produces more carbon.

>Meat is also easy to cook and eat. It digests nicely. It can be used in mono diet with no immediate ill effects. It's a no-brainer food even an idiot can use to sustain themselves. It's hard to poison yourself with it because if it's not fresh it stinks like hell.

I don't think any of those are the main reason people eat meat. In a different comment you say rice, potatoes or lentils are easier to cook such they taste good. I don't think meat is easier to cook than other foods.
