Drones can be made in ordinary civilian houses and apartments. It's too expensive to dig an underground factory just for that, and even if they do (let's assume an abandoned mine could be used), they would still have vulnerable power supply and vulnerable transport. Power plants, transmission lines, rail tracks, bridges are part of the targeted infrastructure. The further they are from the front, the more a logistical nightmare it becomes to move them to where they're needed.
I would guess that there's a big difference between assembling a drone (which can easily be done in a kitchen) and mass-producing parts such as batteries and gas engines for drones that have to fly more than a few dozen kilometers.
Even a single Group 3 UAS like Shahed is larger than a lot of kitchens. They can't be assembled in civilian houses.
You're confusing short range, highly Ukraine-specific Group 1 quads with long range OWA drones.
