Rubbish. Any quote?
HERE:-
Inertia is a function of GS, not IAS
HERE:-
Shortage of inertia (GS) can only be corrected by applying extra thrust
and HERE:-
As you say, no velocity is absolute; it has to be relative to something. However, astronauts excepted, pilots and humans usually measure it in relation to the local surface of mother earth.
You meant momentum, but were still wrong.

Examples?
Here:-
If it's "Horlicks" to state that, for a given mass, inertia (kinetic energy) is a function of GS, perhaps you can tell us what else? IAS?
(Actually, that belongs in both columns)

And most notabley Here:-

While doing so, he may have ample time to discuss whether his "scalar" kinetic energy, and the amount it needs to increase, is relative to an unsteady atmosphere, or to a stable platform like the earth's surface; I shall leave him to that.
If you had simply given an explination of Gs Mini- A way of allowing for windshear by carrying sufficient IAS to allow for it, referenced to a ground speed, all would have been fine. Your delving into iffy physics was always going to be challenged- it is Tech Log after all.

BTW, what happens to an aircraft flying with a large headwind if it quickly turns 180Deg??
