The answer of your question lies in your question.
It is the theorem to be applied to static electric charge.
Still I shall try to find out another answer.
When we measure capacitance of coaxial cable a battery is connected between conductor and braid at one end other end is open. We calculate cylindrical capacitance using Gauss law. This is the case of statical electricity.
But when we measure the on line water bath capacitance(in production of telephone cable ) the conductor is moving through the measuring head( i.e. charge is moving ) and it is measuring accurate capacitance.
The theory says about the free charges enclosed in the volume in question. If the total amount of charge leaving or entering is zero i.e. it can be applied to moving charges too.
Gauss law is one of the set of Maxwell's law which are fundamental law of electrodynamics.

Moving charges requires application of Ampere's Law. Gauss's Law is a static equation.

Yes, in the case of a uniformly moving body of charge composed of single smaller charges.....
