How do you know that? Methane is an important and potent greenhouse gas. Livestock emissions are a significant contributor to methane emissions. As you acknowledge, other efforts to restrict many other types of direct emissions from burning fossil fuels (like shutting down global air travel for two weeks) would be very disruptive. So isn't it worth studying other sources of GHG emissions to see whether there are other opportunities to reduce those emissions that might not be as disruptive? Studying livestock emissions to see if changes in diet, breeding stock, environment, enclosures, or anything else might be a lower cost per unit of reduction than something as drastic as grounding global air travel? You don't know unless you study it.

The premise of the studies isn't to actually study cows. The premise of the study is to justify getting rid of them. That's in the "How about no?" school of compromise.
