Yeah but now you gotta spend MUCH more time because of simple biology and logistics: You wanna eat the muscle of the animals, but the muscle tissue only develops if the animals move… you need much more animals and your feed is going to simple scaffolding stuff like bones and fur. Now you gotta grow more feed to feed your livestock. Welp, now you have smaller area per animal so they move even less (i.e., muscle growth is reduced even further)… what do we do? Vertical farming!
