Bad analogy, IP's are not owned by the person it is registered to at the time. It can also change over time depending on the providers DHCP setup, and ISPs keep terrible logs at times.
Your license plate, is registered to you, or at least to the owner, this is also why camera tickets are a fine, but no points, when it comes to these types of things, it is the owners responsibility to know who is in control of their vehicle, and will suffer the consequences should the person in control do something stupid. Your registration does not randomly rotate to another vehicle like an IP can to another user.
Drones.. well that's new territory, I'm sure we will come up with something, but some laws do still apply, yes the drone can take images of your property, but if the drone parks off in front of your window and records you inside, well thats peeping tom/stalker territory and there are laws that cover that.
What if I walked up and down the street in front of the Mayors house, wrote down every plate I saw for a week.. you bet your ass the cops would show up and possibly not arrest me, but definitely take me in for questioning
