Why should the platform matter, when the alleged goal is "privacy" and the taking of pictures?
The law reacts to a perceived problem, written by people who are primarily adept at things like fundraising and image management.
"residency" and "citizenship" are prerequisites for the job. "Writing good Legislation 101" isn't.
Should there be a law that makes it illegal to use a tripod with a camera to take pictures of people that violate their privacy? How about using a stedi-cam to do the same thing?
These don't generally allow different vantage points than just holding it. So the rules and norms for already in place for photography are reasonably adequate. A drone enables a heretofore generally inaccessible vantage point. It is the new "problem" in question.
Can I throw my camera up in the air to get over-the-fence shots?
If that actually becomes a widespread problem, then we can expect a new law to be passed.
Just as a law was recently passed in response to someone taking upskirts after it was found the existing laws didn't close off the loophole the photographer was using.
You are right, in the sense that the law outlawing the 'platform to take photos' is silly, that it should be a law defining what a "privacy invading photo" is and then outlawing that.
But that's ultimately a circular argument, since the definition is going to be one that includes "taking low altitude shots of people otherwise unaware, from vantage points a photographer could not normally stand, such as from a drone" anyway; and some smart ass is immediately going to ask... "what I drop my camera on the trampoline and it bounces up goes off and just happens to snap the neighbors back yard, am I a criminal now?"
The issue is not "should be", it is a matter of legality.
The law is an very imperfect expression of what society wants the rules to be, usually written re-actively to problems as they arise.
If your complaint is that its a pretty shitty system, then we agree. :)
If your complaint is that you should be able to take photos of your neighbors yard from a drone, then we don't.
