First, the right to privacy extended all the way to the heavens until planes and helicopters became an efficient means of transportation for the common good. The privacy to the heavens became obsolete. Now, we have drones. They are unmanned. They do not provide transportation for the common good. They are used for police departments and governments. Society is not prepared to accept an invasion of privacy by drones, nor is society prepared to accept spying drones as a reasonable search.
