  It's easy to say "you are just wrong" without actually explaining why.

  Attach the cable to the opposite side of the parent body. What happens?

  Besides, we can just forget the cable: Simply shoot the projectile and
that's it. With the correct amount of speed it will stop the object from
rotating. Where did the angular momentum go?

  Since a spinning object can be used to produce energy (eg. by friction)
you are effectively saying that a spinning object is an infinite source
of energy because its angular momentum will never disappear.
