It's not our job to make the world safe for fundamentally unsafe people.
To a degree, yes - but I think if it's taken too far it becomes a trap that many people seeking power lay out.
Benjamin Franklin said it best: "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety."
That being said, I do agree with part of your point. The purpose of having a society is that collective action lets us do amazing things like build airplanes, that would be otherwise impossible. In order to succeed at that we need some rules that everyone plays by, which involve giving up some freedoms - or the "social contract".
The more of a safety net a society provides, the more restrictive the society must be. Optimizing for this is known as politics.
I think history has shown us that the proper balance is one where we optimize for maximum elbow room, without letting people die on the streets. Trying to provide the illusion of safety and restrict interesting technology to protect a small percentage of the population is on the wrong side of this balance.
Maybe we try it, and see what the effect actually are, rather than guessing. If it becomes a major problem, then address it - in the least restrictive way possible.
