a justification of some kind
If we accept the original framework of "you're allowed 95% utilons and 5% non-utilons", then it can still fall under the "allowed non-utilon" category.
If we were to take the other option and try to defend this as an optimal expenditure of money, it might be defended as an act of civilization-building. None of the charities you list will decide the fate of the world; they all depend on the existence somewhere else of a functioning self-sufficient society with spare capacity. Frankly, if you really do take the big picture, it is far from clear that any of those activities matter very much. Civilizational directions are not usually set by what happens in the most unfortunate places.
So if we swing to a different extreme and consider whether high-tech futurist activities might be the best place to spend money, then there's a different challenge - why spend your money on helping to make a single cryonic suspension happen, rather than on FAI research, brain modeling, or wherever you think the most neglected area is.
But actions of a different kind also matter. People who are attuned to these topics need to shake off the distractions of an uncomprehending world and remind themselves of why they took the ideas seriously to begin with. One step leads to another. Unless we just have a singularity first, a day is going to come when there's a lot more than just one desperate person, out of the 100,000 who die every day, seeking cryonic suspension.
When it really, finally dawns on the human race at large that cryonics might work, that a slightly more advanced medicine might cure most causes of death even without cryonics, etc., there is going to be mayhem. Sorting out a rational balance now between self-preservation, conventional charity, and futurist charity may do a little to alleviate that mayhem when it arrives; and it's clear that none of these activities should be wholly absent in the right balance. So we absolutely need to figure out how to accommodate something like Kim's situation into our "optimizing", rather than just putting it to one side.
Saw this on reddit.

I couldn't help be moved by this. I felt a very strong sense that she is one of us, whoever "us" is. Looking at some of the negative comments and worst of all bad arguments people are using as reasons not to donate made me more upset.
I hope some here might join me in dismantling them. I'd also encourage those like me for who this buys a lot of warm fuzzies to donate. Though it might be wise to wait until we hear from CI or some other third party on the matter.
Edit: She has since made a comment on LW! The provided information has made me pretty much certain that this is a genuine plight.
redditors where willing to give her money to go skydiving, they don't want to give her money to buy cryonics. Sometimes I can only weep.
I think it pretty clear that promoting efficient charity in that particular thread is very unlikely to result in people giving money to better causes. Also I just plain want her to be rewarded in some small way! Note the part starting in the second paragraph that I bolded, not only did she realized what she really was, but she stepped over the entire set of pro-death rationalizations and faced the social pressure people she loved exerted on her because they think she might go to heaven ... its not her fault that a few cells in her brain went haywire before she could afford an insurance policy, I just don't want people like that not having something to show after getting so much stuff right.
2n Edit:
For anyone who just realized the universe sucks and wishes to do something about that whole people dying thing, they are welcome to engage in some optimal death defeating philanthropy by donating to The Brain Preservation Prize that has been endorsed by both Robin Hanson and Eliezer Yudkowsky.
