Really agree with this style of reasoning.
It’s worth pointing out your case is weakened by the cases of Kim Suozzi and Aaron Drake, both of whom had their suspensions paid for by the community within the last few years.
It’s also worth pointing out that there has been at least one attempt to give away an Alcor membership to a random person (chosen by lottery). The person who won it ended up not going through with the sign-up process. This was discussed on Mike Darwin’s blog (I can’t easily find the link right now, but lmk if you’re curious).
Also, some in the cryonics/brain preservation community have donated to research and logistical investments that would certainly not benefit themselves only.
ETA: Another point here is that because of the tricky informed consent and possible negative outcomes following brain preservation, it’s much more difficult to choose for other people to be preserved rather than choosing to preserve oneself.
Can you please explain what you mean by “anti-aging fetish”?
I think the cost of brain preservation procedures and financial accessibility is extremely important. As I mention in the post, some of the options that are already available today are relatively cheap, costing a few thousand dollars. This is cheaper than the average funeral in the United States. With more research, the procedures could potentially become cheaper. In my view, brain preservation would ideally be free to the individual and paid for by philanthropy or health insurance, so that there are no financial accessibility problems.
Of course, whether any of these procedures will actually work is an open question.
I’m not sure if the cost of the procedure is what you are concerned about, though. Is there some other reason that you think that brain preservation would only be for the benefit of extremely rich people?
