Yes, but the discussion is part of the way that we do it. Not only do we have to have the discussion, but the discussion makes sense the same way that Newton’s laws make sense for billiard balls.
You wouldn’t say “These billiard balls are just going to move around deterministically anyhow, so it doesn’t make much sense for them to conserve momentum.” :P
