When applying your objections to my own perspective, I find that I see my actions that aren't focused on reducing involuntary death (eating candies, playing video games, sleeping) as necessary for the actual pursuit of my larger goals.
I am a vastly inefficient engine. My productive power goes to the future, but much of it bleeds away - not as heat and friction, but as sleep and candy-eating. Those things are necessary for the engine to run, but they aren't necessary evils. I need to do them to be happy, because a happy engine is an efficient one.
I recognized two other important points. One is that I must work daily to improve the efficiency of my engine. I stopped playing video games, so I could work harder. I stopped partying so often so I could be more productive. Etcetera.
The other point is that it's crucial to remember why I'm doing this stuff in the first place. I only care about reducing existential risk and signing up for cryonics and destroying death because of the other things I care about: eating candies, sleeping, making friends, traveling, learning, improving, laughing, dancing, drinking, moving, seeing, breathing, thinking... I am trying to satisfy my actual preferences.
The light at the end of the tunnel is utopia. If I want to get there, I need to make sure the engine runs clean. I don't think working on global warming will do it - but if I did, that's where I'd be putting in my time.

His answer, as far as I can tell, seems to be that his Azimuth Project does trump the possibility of working directly on friendly AI or to support it indirectly by making and contributing money.
It seems that he and other people who understand all the arguments in favor of friendly AI and yet decide to ignore it, or disregard it as unfeasible, are rationalizing.
I myself took a different route, I was rather trying to prove to myself that the whole idea of AI going FOOM is somehow flawed rather than trying to come up with justifications for why it would be better to work on something else.
I still have some doubts though. Is it really enough to observe that the arguments in favor of AI going FOOM are logically valid? When should one disregard tiny probabilities of vast utilities and wait for empirical evidence? Yet I think that compared to the alternatives the arguments in favor of friendly AI are water-tight.
The problem why I and other people seem to be reluctant to accept that it is rational to support friendly AI research is that the consequences are unbearable. Robin Hanson recently described the problem:
I believe that people like me feel that to fully accept the importance of friendly AI research would deprive us of the things we value and need.
I feel that I wouldn't be able to justify what I value on the grounds of needing such things. It feels like that I could and should overcome everything that isn't either directly contributing to FAI research or that helps me to earn more money that I could contribute.
Some of us value and need things that consume a lot of time...that's the problem.
