How about making these smaller and smaller until they are just resemble swarms of insects ?
I wonder if there are any projects that are starting the process from the other side : take a mosquito and bio-engineer it somehow to use as a micro surveillance platform. I wouldn't be surprised if DoD already has such projects underway.
As the size gets smaller, FAA radars won't be able to detect these anymore. They might have to scan the control frequencies perhaps and triangulate to the base station.
It would become harder to get caught, but could remain illegal nonetheless; which prevents from building a legit economic activity around them.
As for radar signature, the smaller drones are already barely bigger than a large bird, so I guess they aren't spotted by radars, or at least not recognized as UAVs.
