That's equivalent to suicide. You could do something similar today to eliminate sexual or other desires, but people aren't doing it. I assumed they can replicate at the lab. Care about who? Other oligarchs? If there are other oligarchs(which is not necessary, since it could be one king and few thousand people below him), then he would receive benefits from them and vice versa. Most people don't care about pushing human(ity) further, just want the current entertainment flavor of the generation. Why should the lab-creator care about them ? Just because someone pays for your job, doesn't mean it should exist, ex: gossip magazines. And when you have no work/purpose, why should you exist ? To consume finite resources? He may think the same thing for other oligarchs. Who will try to kill them? Masses or other oligarchs? If you build a life-extension (or a human backup+restore) lab you'll be at war with whoever you don't want to share. What others? Other oligarchs with different labs? 2 main ways to change the world would be: Kill those who oppose you, or build better tech and don't save them (but those will better weapons will kill you first). The more you automate and advance, the easier it would be to not need(and pursuing of not needing) other oligarch/normal sheeple.
