You're right, outlasting everyone is a way to suck less. But it's not a real way to be the best. Being the best and sucking less have similar starting steps but very different ending steps. Where you stop on your list and write "repeat" is where the journey to being the best just begins.
I don't know about you, but I never want to just be mediocre. I want to be really damn good at whatever it is I try. Even knowing that one of the greats could "come out of retirement" and still out-do me is not good enough for me. That's just patience resulting in complacency and mediocrity.
