It's not just the limitations of satellite tech or quantity. There's also just the fundamental limit of RF in shared airspace. You run into bandwidth limits due to interference even without overcrowding low earth orbit with a satellite network. When you're running signals over a wire/fiber, your signals are confined and interference is managed relatively trivially.
