Of course the rotational form of the second law to which you refer can
always be used with an accelerating origin provided one accounts for
torques due to so-called "frame forces"*. In those special choices of
origin for which frame forces produce zero net torque one may apply the
law thoughtlessly without suffering an error in the answer. However,
would it not be better to apply the law thoughtfully and recognize that
the frame force forces contribute zero net torque with proper choice of
origin? Is this so different from choosing any other origin because it
simplifies calculation?
