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.
Could you please flesh out your reasoning for this a little bit more?
It seems to me that there is a large difference between your two scenarios, with much larger utility going to extending existing people’s life rather than creating new ones.
This is because an extremely large cause of disutility for current people is the fact that they will inevitably die. This prevents them from making long-term investments in their own happiness, their local communities, and the world at large. Evidence for this abounds, and includes strong rationalizing behavior towards death. Atul Gawande also discusses it in his book Being Mortal.
