I haven't seen a study deeply analyzing non-food uses either. I suspect though that while there will indeed be replacement costs they will be less than the costs of continuing the current system.
Michellin apparently already makes "vegan" tyres. Even for cat food, there are already vegan supplements and the science will improve. Beyond Meat being only 2x the price of killed meat is I think quite impressive when you consider how long each industry has had to optimise.
Yes switching from cows to chickens is better with regards to carbon but the problem is it's much worse with regards to animal welfare since many more animals need to be killed per kilo of meat..
There could be an optimal level of meat consumption if you just consider the environment, but it's far below what we're doing now, and given the urgent climate action that's recommended by expert scientists, it seems wise to reduce this consumption as much as possible. We're _far_ more likely to reduce too slowly than too quickly..
