The question is why do inertial frame exist. No GR does not
answer that any more thane Maxwell's equations answer the
question why do electric fields exist.

Reference frames are imaginary.
A mechanism that can store energy when you push it and
release that energy by splashing into a bucket of water
and do it conservativly, near or far from a massive body
is quite real.
An electro-dynamic theory of the 'mechanism' is being suggested.

We see GR-POiNT-mass on TiME-lines (WORLD-lines) in SPACE-time.
