Here's a follow-up question, though: one can temporarily create small

required to unify electromagnetism is really small already, one ought
to be able to do that to much larger regions, so couldn't one avoid
the catastrophe through a bit of megaengineering to ensure that the
region of your solar system (or even just your planet) remains
sufficiently hot?
Actually, mega-engineering might not be necessary to avoid this.
The EM gauge symmetry would break when the vacuum fell below some
temperature, which has to be lower than the current background
temperature.
Near a star, it's always going to be hotter than that. All the
stellar photons are far more energetic than the symmetry-breaking
scale, so they'd keep it unbroken.
Each star would be at the centre of a bubble, outside which
the vacuum becomes opaque.
That provides a solution to the Fermi Paradox -
in interstellar space, EM decouples and things break
down. Interstellar travel becomes impossible.
Doesn't work right now, though...
