Einstein's residual potential has been lost, because he is dead. He was still writing papers in 1955, when he died. If he was still alive, I hope he would still be publishing. The idea that "residual potential lives on in others" is irrelevant - there should be no need to die to inspire someone else. Moreover, even if inspired by Einstein, no-one will not produce exactly the same work as Einstein would have, had he lived. So that notion is refuted, and would become ever more definitively so over the accumulated years and contributions of an indefinite lifespan. Solving the problem of death includes removing the overwhelming preference for death in cases where it is the only relief from a terrible quality of life, so your chronic pain example gets swept aside. The is no such thing as a "hedonovat" and your depiction of it sounds frankly ridiculous. Hoping to enable an indefinite human lifespan with a high quality of life is not ridiculous. Death is only loss and pain.
