I hear what your saying but it’s at best a matter of scale.

Slaughtering the cows would be like... selling her car so her mom can’t use it. Her mom can’t hurt the cow anymore, sure, but there’s still no fence there.

In contrast, telling her mom “No, you can’t use my car” would be setting a boundary. But telling her mom “I don’t want you in my life” would also be setting a boundary. These are just two different fences. In both cases, the cow/car are just fine.
