This is correct. But the surgical precision is only enabled by the fact that a person can be reasonably well located and tracked. It's likely not hard to pinpoint a specific person of interest in a vast metropolis, but, IMHO, really hard or impossible to locate a specific wild zebra in an African savanna, because they do not wear tracking devices, and inhabit large areas. So you can target e.g. me in NYC much more easily than some specific zebra, even though the zebra is likely less intellectual and less privacy-conscious.

Hence, I suppose, important figures will eventually disappear from the public eye. Definitely, a president or a governor must be present in person at many events. But e.g. CEOs of military contractors, or even key scientists and developers in certain fields, may start to fade away, turn pseudonymous, and virtualize, now that remote work and videoconferencing is normalized. They would still be somehow trackable as normal citizens, but their visible connection to their work would be severed and kept an utmost secret, literally a life-and-death secret.

This would be good news for national defense, but bad news for any dissenters who cross any powerful-enough entities for those to consider an assassination or at least blackmailing. Unlike a hitman, a hit drone can be completely and safely destroyed beyond recognition within an hour, by burning it and grinding the ashes.

Also, precisely delivered non-lethal means could be quite effective, and hard to track. Inject or just spray a bad virus to disable your opponent for several critical months. Spray a potent allergen if the target is allergic. Inject some LSD into politician's bloodstream an hour before an important meeting or speech. "Innocent" stuff like that.
