I'm absolutely stumped by this kind of arguments. I have to get back to what Eliezer calls "belief in belief" to process this - you can't possibly actually believe that, you just have a belief that you do. Because since there's nothing in this train of thought about us happening by chance to have the exact optimum lifespan right now, the logical conclusion is that we should work on people having shorter lifespans in order to live better, more community-rich lives, at least up to the point where you get diminishing returns.
