(Edit: after having written this entire giant thing, I notice you saying that this was just a "why are some people not interested in cryo" comment, whereas I very much am trying to change your mind. I don't like trying to change people's minds without warning (I thought we were having that sort of discussion, but apparently we aren't), so here's warning.)

But it seems that natural death seems like a good point to say "enough is enough." In other words, letting what's been given be enough.

You're aware that your life expectancy is about 4 times that of the people who built the pyramids, even the Pharoahs, right? That assertion seems to basically be slapping all of your ancestors in the face. "I don't care that you fought and died for me to have a longer, better life; you needn't have bothered, I'm happy to die whenever". Seriously: if natural life span is good enough for you, start playing russian roulette once a year around 20 years old; the odds are about right for early humans.

As a sort-of aside, I honestly don't see a lot of difference between "when I die is fine" and just committing suicide right now. Whatever it is that would stop you from committing suicide should also stop you from wanting to die at any point in the future.

I'm aware this is a minority view, but that doesn't necessarily make it any less sensible; insert historical examples of once-popular-but-wrong views here.

Most people who try to make all their beliefs fit with all their other beliefs, end up forcing some of the puzzle pieces into wrong-shaped holes.

Then they've failed at the actual task, which is to make all of your beliefs fit with reality.

When we get to human values, some of them REALLY ARE in conflict with others,

My values are part of reality. Some of them are more important than others. Some of them contradict each other. Knowing these things is part of what lining my beliefs up with reality means: if my map of reality doesn't include the fact that some of my values contradict, it's a pretty bad map.

You seem to have confused people who are trying to force their beliefs to line up with each other (an easy path to crazy, because you can make any belief line up with any other belief simply by inserting something crazy in the middle; it's all in your head after all) with people with people who are trying to force their beliefs to line up with reality. It's a very different process.

Part of reality is that one of my most dominant values, one so dominant that almost no other values touch its power, is the desire to keep existing and to keep the other people I care about existing. I'm aware that this is selfish, and my compromise is that if reviving me will use such resources that other people would starve to death or something, I don't want to be revived (and I believe my cryo documents specify this; or maybe not, it's kind of obvious, isn't it??). I don't have any difficulty lining up this value with the rest of my values; except for pretty landscapes, everything I value has come from other humans.

In some sense, I don't try to line this, or any other value, up with reality; I'm basically a moral skeptic. I have beliefs that are composed of both values ("death is bad") and statements about reality ("cryo has a better chance of saving me from death than cremation") such that the resulting belief ("cryo is good") is subservient to both matching up with reality (although I doubt anyone will come up with evidence that cryo is less likely to keep you alive than cremation) and my values, but having values and conforming my beliefs with reality are totally separate things.
