When gravity froze out from the other three forces just as inflation began.

You could imagine that when the initial symmetry of the universe was broken, that may have produced rather large gravitational disturbances that inflation smoothed out. Remember, according to theory, the cosmological constant at the time was highly non zero, so gravity may have been predominantly repulsive instead of attractive. Inflation would have been driven by this, however in the process of inflation, the expansion would've greatly reduced the initial value of the constant, hence the effects of gravity (or it's antithesis if you consider it not to be gravity, per se).
