GR lives without a notion of an "inertial frame" and is doing fine.
To search for an inertial frame you have first to define its meaning.

I have already done that for you. If you disagree with it,
which apparently you do, then argue that and not that I
have yet to define it. I have said that I-frames are not
real objects, but a figment of our imaginations, so we do
not "search" for I-frames, we create them.

And this is a definition? At best, it is a phrase which
defines some of its properties.

A system of coordinates where every worldline defined by
x^i = const is geodetic?

Even if that is so, I did not invent the concept - I am only
explaining it.

In GR there is no such concept. Tell me who invented it
in GR.

A notion of an "I-frame of observer x" is not known in GR
and I see no reasonable way to define it (the definition I
suggested defines only a global property of being an
"I-frame", without dependence of observers.

If you will note the subject of this topic, you will see it
does not refer to GR.

The CMBR is not covered by SR.

That is an acknowledged fact, the CMBR exists
in an expanding universe which is outside the
domain of applicability of SR.
