I think immortality(the “living forever provided im not vaporized” kind) could never be reserved to a select few, what can be reserved to a select few is a highly advanced drone swarm armed with lasers that can vaporize a crowd of angry commoners. You understand?

I find it hard to believe that governments can keep a monopoly on violence with how powerful some families/people have been getting, there will be a divide but it wont be a mortal/immortal one its not that simple
