Doofus, sometimes bearings do get removed and reused. Like when you have an integrated brake drum or rotor that is damaged or worn beyond limits. In those cases, care must be taken not to damage the race when it is removed. But if you know in advance that the race is going in the trash can, which would probably be the most likely scenario, there is little point in using a brass punch to protect a part that is not intended to be reused.
