You will change your mind when you visit a corporate farm, then you may not. Heard of meatrix? Next time you're at a restaurant visit the kitchen, it's disgusting what's going on back there. If your kitchen is anything like this, you should burn down your home.
Industrial farming, especially industrial animal farming, is not exactly a pleasant sight. On the other hand that's the best way to keep food prices low.
I am aware of these alternatives and I support the idea wholeheartedly. The question is how long it will take for the price to drop sufficiently.
