Any of these types of things said about factory farmed meat is correct. For free-range meat, some of the production does cause habitat destruction. However, most animals are raised on land that is not highly productive for crop agriculture. For example dry areas where most crops will deplete water resources or very hilly areas that are more prone to erosion and harder to operate tractors on, etc (this is even mentioned in the our world in data link). So meat and crop production are not a zero sum game and can even be complementary (crop farmers used to always have chickens, etc).
In a grassland environment one can maintain a close to natural environment with the birds and bees with the difference being that cattle are the only megafauna and cattle predators will be killed. Raising crops means completely altering the environment to an unnatural state that then this report tries to amend and killing all the gophers and other pests along with using pesticides, herbicides, fungicides, and other chemicals (yes organic farming can reduce this harm).
