And where is our supposed error ?

We can choose as the reference the coordinate system of a stone in rest.
( even if it would not be a good idea.)

Any choice of a coordinate system is arbitrary.
Even choice of a natural coordinate system, as one choice of many.
We arbitrarily choose coordinate system, being natural or not.

The speed of a bullet refer to a coordinate system,
where you evaluate it.  It is naturally arbitrary.

Before making statement about speed of sound,
you should make clear what its meaning you mean,
as validity of statement depends on it.

1/referring to coordinate system where medium is in rest.
2/referring to arbitrary coordinate system

Would you speed of light in air during laser precise measurements
refer to the devices or to air ?

Natural in the sense of being close to human mind
is arbitrarily choosing the natural one,
not being given it in advance.

BTW, it is not the only possible natural choice.
Sun centric ecliptical system is natural system as well.
To me, arbitrary choice from natural systems sounds reasonable.

Sure, is not it self - obvious ?

although Einstein was inspired by this fiction writer.

Sure, is not it self - obvious ?

Light does not have its own coordinate system,
where it would be in rest. It has local speed c
wrt all locally inertial coordinate systems,
if I am widening the scope toward GR.
