I do not happen to think that cryonics should be **illegal**. I think people should be free to spend their money, and dispose of their corpses, as they see fit (in the latter case, as long as it doesn't create a public health hazard, of course).Yeah, that's how I feel about it, too. Certainly the official verbiage of the organizations shouldn't be allowed to create the false and fraudulent impression that the current state of scientific knowledge provides any grounds for actual confidence that severed hamburgerized heads will be nanobotically or digirifically resurrected or whatever -- but it seems to me that contra the handwaving of True Believers in faithly settings the organizational discourse covers its ass more or less. Beyond that, so long as you say as there is no hazard to public health, it doesn't seem to me on the face of it that cryonics should be any more illegal than embalming is, or cremation, or shooting corpses into the Sun or what have you.
Myself, I always rather liked the fictional depiction of the Bene Gesserits on Chapterhouse dropping bodies in orchards with a freshly planted tree on top of each departed member of the community. I rather like the idea of a white-petalled dogwood flowering on a hillock where I used to be. I remember driving past woods in Indiana as a kid when dogwoods were blooming among the trees thinking the forest, like the monolith in 2001, was full of stars.
