It's not so simple. Technology is a race between offense and defense and right now we're seeing offense leapfrog defense. The status quo that we've known our whole lives has meant that anyone trying to assassinate a powerful figure will only get one shot at it before they're caught which does not allow them to learn from their mistakes and sends a chilling message to others who would do the same. With remote controlled or autonomous drones the dynamic changes because people can operate from a distance -- perhaps even in an entirely different country that doesn't extradite. What's the defense against that? At the end of the day the attacker only has to succeed once whereas the defender has to succeed every single time. There may come a time where the ultra-wealthy and powerful decide that it isn't viable for them to be out in public due to the security risks so they will retire to a gilded cage -- which is still a cage -- and what's worse it reduces the search space for attackers to find them. This doesn't even get into the near future advancements in biotechnology that will allow small groups of dedicated people to develop biological weapons that selectively target a wealthy person's family -- how can they defend themselves against that other than going into a fully sealed environment? At the end of the day it'll end up being easier and better for these people to just make decisions that benefit the world at large instead of decisions that benefit themselves to the detriment of everyone else. If you piss less people off less people want to kill you and in fact more people will want to defend you.
