I come at it from a non-commercial perspective; at most I've had two hives at a time. I was mostly speaking from personal experience of winter losses; it's really heartbreaking. Commercial hives are indeed relatively mobile, as they're temporarily stored on trucks to move from field to field. It's possible that it's simply untenable to keep bees indoors on a large scale. Hives that are too close together for long periods of time will attack and raid each other. There simply might not be enclosed spaces large or affordable enough to hold wintering bees. But someone who does commercial bee-keeping could probably give you a much better answer.
