> you are just down some bizarre philosophical rabbit hole if you truly believe that
What I've said isn't anything radical, and like I've mentioned above, this is a common tenant of pretty much every ethical system that life is an end in itself. This perspective is outlined in Nozick, Kant, Scanlon, Nagel, Rawls and countless others. Some of these authors have influenced the legal systems of entire nations. Rawls and Kant, for example, are considered "main stream" ethical theorists.
> Under this logic policing is unacceptable
No, because as I've already stated, justified self-defense is a different situation entirely. The situation of extrajudicial killings by police is, however, unacceptable.
> vaccine research is unacceptable, driving a car is unacceptable
This is a false equivalency. The key difference here is the informed consent that's associated with the actions. Nobody is consenting to having their confidential data released. In the above situations you listed, one of the stipulations of engaging in, say, a vaccine trial, is a clearly stated risk. A vaccine trial on someone unwilling is wrong. Someone who willingly agrees to 'open-source' their data and gets killed as a result is also in a different situation that the one we are discussing.
To pretend that someone who's willingly engaged in a dangerous activity and died has experienced the same sort of wrong as someone who'd date was leaked against their will, and as a consequence was murdered, is just nonsensical. Notice how I said "if anyone dies as a result of this" not "anyone dying makes any situation automatically wrong".
If I walk on a sidewalk and get hit by a car, I am the one who decided the sidewalk's risks were worth it. There was no gun to my head. As my life is mine, I can dispose of it and use it as I see fit. That's not something anyone else can do or decide for me.
