Fiber optic cables have a much much higher usable bandwidth than the wireless spectrum. The useful radio spectrum for Starlink is somewhere between 10 and 20 GHz. Fiber optic cables have more than 4THz of usable spectrum. And it's no affected by things like fog, rain, strong wind (at least if you don't cheap out and stick it on poles), etc.
