But without any sensible regulation or assignment of property rights to fly commercial drones, advertising drones could be buzzing around everywhere! To limit the ability of stores to put signs wherever they want, the are both signage/billboard regulations. If a store can't secure a billboard at a desirable intersection, they sometimes pay to put a person with a sign there. That loophole is only acceptable because there is a cost of the employee that creates a natural cap on the use of unregulated signage. With the advent of drones, the cost of will fall dramatically and the expected result is an exponential proliferation of such drone signs. Yes, current battery technology is woefully incapable of this currently and autonomous technology isn't there yet, but as soon as the drones can be 100% autonomous and can recharge themselves on charges on the roof of a nearby building, then it simply becomes a capital cost of the drones. I think at that point is won't be simply for publicity stunts anymore. Let's hope this isn't the future we find ourselves in.
